The Hebrew word for corner is Pe'ah meaning the 'side' and the word for 'stone' is Eben with the implication to restore or to build a house or family. This is very interesting because the word for House in Egyptian carried the notion of the house being the woman as in Hebrew the Beth or Bath being the female 'wife of' or 'daughter of'. When the people of the region called on the 'House of a Man' whether a King or Pharaoh the wife was the object making or being that house. In this sense the word stone or Eben with the prime root word of 'Banah' in Hebrew can represent a family or house of a person. 

There is a word 'headstone' found in Zechariah 4:7 that would have been more applicable when looking for the equivalent 'capstone' where the Hebrew word Rosh or Rosha [fem.] is used as the pinnacle, beginning, head, top. But in Isaiah. 28:16 the translators make the leap that the corner is a cornerstone an uses the word Pinnah, used a Mural tower or a Prince of the people.

"Therefore thus says the Lord GOD: "Behold, I lay in Zion a stone for a foundation, A tried stone, a precious corner [stone], a sure foundation; Whoever believes will not act hastily."  Isa. 28:18.

BTW: I found this side-note interesting the word for hate or hastily in Isa.  is the Hebrew word Cush or Kush. But the translators separated the Kush and Cush and made each have a different meaning although pronounced the same like Tom-A-to and Tom-AT-o, but it is all the same vegetable or fruit. 

Quote by Maulana Karenga from the translated sacred wisdom books he calls the Husia--pg xiv.

"One can appreciate the need for exact translations but literal translations are not always exact or correct. For example, one can translate the Swahili sentence "Wanasema Kizulu kama maji" literally and get "They speak Zulu like water". But it figuratively and correctly means "They speak Zulu fluently."

Transliteration is the practice of transcribing a word or text written in one writing system into another writing system.[See my essay on [Translation, Transliteration and Versions]

Transliterations in the narrow sense are used in situations where the original script is not available to write down a word in that script, while still high precision is required.

Transliteration in the broader sense is a necessary process when using words or concepts expressed in a language with a script other than one's own.

Example:

The idea of transliteration is complicated by the genuine use in multiple languages of different common nouns for the same person, place or thing. Thus, "Muhammed" is in common use now in English and "Mohammed" is less popular, though there are excellent reasons for each transcription (and similarly for "Muslim" and "Moslem").

Could this be the same for Kush and Cush? How is the word for Cush said to mean black and the other word for Kush said to mean excitement or enjoyment? It was the choice of the transliterators.

2363 Chuwsh koosh a primitive root; to hurry; figuratively, to be eager with excitement or enjoyment:--(make) haste(-n), ready. חוש

3568 Kuwsh koosh probably of foreign origin; Cush (or Ethiopia), the name of a son of Ham, and of his territory; also of an Israelite:--Chush, Cush, Ethiopia. כוש

How would that scripture read otherwise using Cush the people instead of the word haste?

"Therefore thus says the Lord GOD: "Behold, I lay in Zion a stone for a foundation, A tried stone, a precious corner [stone], a sure foundation; Whoever believes [not-not] in Cush."  Isa. 28:18

That makes no sense unless you look at the word 'haste' in context. Is he laying a Cushite cornerstone in Zion? What was there before and what had Canaan become?  Could it read--

"Therefore thus saith [utter, speak or say ]the Lord [Adonai] GOD [Yahweh], Behold, I lay [found, ordain, establish or fix ]in Zion [a parched place see Zi-On] for a foundation a stone [a memorial or family ], a tried [stable, tried and tested] stone [ family, memorial], a precious [costly, rare, splendid, influential] corner[ chief, corner, ruler, prince of the people] [stone], a sure [ fixed or established family] foundation [a founded-foundation]: he that believeth[ supports, as a foster mother or father, upholds or nourishes that institution] shall not [not or double negative means a positive] make haste [Cush, to feel, excited, enjoys the pleasures of life or to make or continue a family bloodline [Cushite]]."

The word Cush was probably of foreign origin as the Concordance people put it. Probably? Possibly? What foreign origin? Who first called Ethiopians/Africans Cush? Later that same word became a derogatory term for a black man and they began using Shachar. 

"And the sons of Ham; Cush, and Mizraim, and Phut, and Canaan And the sons of Cush; Seba, and Havilah, and Sabtah and Raamah, and  Sabtecha: and the sons of Raamah; Sheba, and Dedan. And Cush begat Nimrod: he began to be a mighty one in the earth ." Gen. 10:6-10

Let us do some word replacement for  a moment. If Cush means black in Hebrew, then let's look at the above scriptures in that context. 

"And the sons of Ham; the Blacks, and Mizraim, and Phut, and Canaan And the sons of the Black; Seba, and Havilah, and Sabtah and Raamah, and  Sabtecha: and the sons of Raamah; Sheba, and Dedan. And the Black begat Nimrod: he began to be a mighty one in the earth ." Gen. 10:6-10

Sounds like everyone in the motherland was covered. I would be genetically impossible for a Caucasian to have a African [Black] son, so Noah had to be a back man too. I think in a rush to separate the entire family a racial designation was put on Cush and he was assigned to be the darker to the three sons. 

We have all come to know Ham or Cham/Kham as Africans and his sons were African too. Why would the translators define only Cush as Black as if to racially separate him from his family in our mind. 

What is the general word for black in Hebrew? Shachor from the transliterated word: Shachar meaning dusky or dark, black and this from the prime root word: shachar meaning to break forth. 

What does the root word to seek have do this dusky or black? It is always darkest before the dawn. You can't see and you can see. a primitive root identical with shachar through the idea of the duskiness of early dawn.

Could this be the same reasoning for the foreign word used for Cush? Cush being delight a place or people that by honoring them you will make haste or have a pleasurable life. Could it be that  he breaking forth is a reference to the original of everything. That life sprung forth in blackness and in the black land? 

So, Cush and Kush although variant spellings and meanings could be the same word and meaning. 

2363 Chuwsh koosh a primitive root; to hurry; figuratively, to be eager with excitement or enjoyment:--(make) haste(-n), ready.חוש

3568 Kuwsh koosh probably of foreign origin; Cush (or Ethiopia), the name of a son of Ham, and of his territory; also of an Israelite:--Chush, Cush, Ethiopia. כוש

The Bible says of Israel : "I will bless those who bless thee.”

I believe the word haste or hastily can be transliterated as Cush just as the word Shachar means both 'diligently seeking' and 'dusky or black' just as Cush which is black can mean enjoyment to hurry excitement and making haste. 

In the book of Neferti from the Husia by Dr. Karenga:

"But a king shall rise from the south named Ameni the vindicated one, the son of a woman of Nubia. He will join together the Double Crown and the land will enclose in his grasp. the people of his reign will rejoice, for Ameni the son of m, will make so name for all eternity. the evil minded plotters of treason will hold back their speech through ear of him. the Asiatic invaders will fall before ho fury and the Libyan invaders will be consumed by his flame. Rebels will yield before his wrath and traitors will be brought low by his might. The, Maat, righteousness and order, will return to its place and Isfet, evil and chaos, will be driven away." pg.87

Amos 5:24:

"But let justice roll on like a river, righteousness like a never-failing stream!"

Let us look at what the  concerning the cornerstone scripture  may mean in a more Egyptian context.

"Therefore the utterance of Aten [Sun] and Yahweh [Moon], Behold, I lay in Zion[ A holy place of On in the Canaanite desert] for a foundation a memorial or a family, a tried and tested family and their memorial [standing stone] a splendid ruler, a prince of the people, from a founding or established family a founded-foundation: and He that supports, fosters and upholds that institution which they represent, shall [shall cause by a double negative of not/not] enjoy the pleasures of life."

The reason I have used Aten in place of Adonai is because the D and T are interchangeable in Egyptian and Hebrew and both languages are consonantal [without written vowels] a proved by Ahmed Osman.

Yahweh was historically represented as the moon [god] and his calendar was lunar.  

"According the Harvard Seminary review: " Scholars are aware the name Yahweh is not Hebrew and was derived by a foreign source..." http://links.jstor.org/sici?sici=0017-8160%28192004%2913%3A2%3C184%3ATBOJWI%3E2.0.CO%3B2-Q&size=LARGE&origin=JSTOR-enlargePage

There were many Yah gods throughout the lands of Egypt, Canaan, and Assyria.  Yah is associated with the moon god in Egypt, with the heifer/cow gods of Jeroboam, and with goat gods."

The place in the desert called Zi-On is a combination word that relates back to an outpost or memorial for On or Anu the Greek Heliopolis were Joseph and Moses were said to have been educated. A standing stone was placed there by the Biblical David and the actual Tutmoses III and Canaan remained a suburb of Egypt for any years. 

"The capture of Jerusalem/Kadesh by Tutmose III also resolves the formerly unknown source of the name Zion. Zion consists of the components On (Hebrew for the holy city of On/Heliopolis in Egypt) and the Hebrew word Zi (meaning arid place). Literally translated, Zion appropriately becomes "Holy City of the Desert." [House of Messiah. Ahmed Osman]."

"The Jerusalem Jews were opposed to the Alexandrian temple, and jealous, because they saw it as a rival temple. When they got their version of the Septuagint, they minutely altered the word for “Sun” (cheres) so that it read “destruction” (heres) instead. Calling On/Anu the City of Destruction or Desolation instead of the City of the Sun or City of Righteousness.

The Septuagint [Greek] version speaks of On/Anu reads “ir-ha-zedek” = “a city of righteousness”, but the altered version read “a city of destruction”. It is because of this tiny variation between the two versions of the Septuagint that the King James and Authorized versions have a marginal note about the alternative reading. The correct rendering is “city of the sun”, or “Heliopolis” is  City of Righteousness. " [Anu]

Tutmoses III was the ruler in Canaan from a family that was said to be Hebrew [sect not race] h mother was a concubine named Isis and his father was from the line that would later produce Ankhenaten that later took the family name Imram [Amram and Yocheved]. They were a royal family a  founding family and by blessing and honoring  them all would prosper under their care and enjoy the pleasures of life.  See my essays on Moses, Anu, Iconography and other for all references to the above.

Names and Titles of Jesus:

The Lord Jesus Christ bears kingly titles. He is King Of Israel (John 1:49; Matt. 2:2).

Christ is typified by the well known heraldic symbol of the lion (Rev. 5:5).

Jesus is further called a Prince (Acts 3:15; 5:31).

Christ is styled as the "Only Potentate, the King of kings, and the Lord of lords" (I Tim. 6:15; Rev. 19:16). A "Potentate" is defined as "a person who possesses great power; a sovereign, monarch, or ruler which is derived from the Latin word "potentat(us)" which means "power" or "dominion."

Christ is head of the church (Eph. 1:22; Col. 1:18). .

II Tim. 4: 8 presents Christ as the "righteous judge." When governmental law was in its infancy all laws proceeded from the king the monarch still has supreme judicial authority and prerogative.

Heb. 1:2 makes Christ "heir of all things" A "heir" is defined as "a person who inherits or is entitled to inherit the property, rank, title, position, etc., of another." 

Christ sits upon a throne (Rev. 4:2; 22:1; see also Psa. 45). Jesus wears a crown (Heb. 2:7-9; Psa. 8:5; 19:12). Also, Christ is christened with the title of "Majesty" a title for a king (see Psa. 145:5]. Modified from: http://www.jesus-is-lord.com/kjcosto4.htm

Isa 9:6

"Wonderful Counselor,  Mighty God, Everlasting Father, Prince of Peace Holy One, Lamb of God, Prince of Life, Lord God Almighty, Root of David, Branch of Jesse, Word of Life, Light of the World, Savior, The Way, Daysrpring, Sun of Righteousness, The Alpha and Omega."

What would these title and name read in Hebrew or Egyptian? What words have been made into Titles? What title was confused for a name? 

Immanuel: God with Us.

"Therefore the Lord himself will give you a sign: The virgin will be with child and will give birth to a son, and will call him Immanuel."

He was never called Immanuel because it was a title just like the current President of the United States carries the title of Commander and Chief. It was is function.

So, if an Egyptian Hebrew called him Pharaoh he would be calling Jesus the "Light of the World!!!!!!"

Then spake Jesus again unto them, saying, I am the light of the world: he that follows me shall not walk in darkness, but shall have the light of life. John 8:12.

Then he says: You are the light of the world. A city on a hill cannot be hidden. Neither do people light a lamp and put it under a bowl. Instead they put it on its stand, and it gives light to everyone in the house. In the same way, let your light shine before men, that they may see your good deeds and praise your Father in heaven. Matt.5: 14

Now, did they change that title of Pharaoh in to a Greek Phrase light of the world?

How can the Capstone reference come into play with the cornerstone from the surface--on the surface they are two differing things in two different positions. But it does not mean that they are not Pharonic or Kingly references for both cornerstone and capstone.

Job 38:5: 'Who hath laid the measures thereof, if thou knowest? or who hath stretched the line upon it? Whereupon are the foundations thereof fastened? or who laid the corner-stone thereof; When the morning stars sang together, and all the sons of God shouted for joy?'

The fruit of what? The understanding of the foundation stone that was laid in Zion the stone that was later rejected by the builders what was then looked on as Hellenistic Judaism and later Christianity. 

Here the word for stone is the Greek word ‘lithos’ meaning limestone.

"...stone was the construction (2600 BC) of the great pyramids in Egypt, the largest of which (Khufu) is 236 metres along the base sides and contains approximately 2.3 million blocks of two types of limestone and red granite. The limestone is believed to have been quarried from across the Nile. Blocks weighing as much as 15,000 kg (32,000 pounds) were transported long distances...Limestone is important because of its use in the cement industry, and deposits are fairly widespread. North Africa is a particularly important source. In western Africa a belt of limestone runs from the Central African Republic to the Atlantic coasts, with major outcrops in northern Nigeria, Niger, Burkina Faso, and Mali. Elsewhere there are deposits in Nigeria, Benin, Togo, and Ghana. " Encyclopedia Britannica

Cornerstone:

"The cornerstone foundations of the pyramid have ball and socket construction capable of dealing with heat expansion and Earthquakes."

"...the idea of the cornerstone--a cornerstone is defined as "somebody or something that is fundamentally important to something." Another perspective comes from a building definition, which is "the first stone laid at a corner where two walls begin and form the first part of a new building." If we take these two definitions and consider their meaning it is logical that we can define a cornerstone as a significant part of the foundation..."

A Cornerstone is fundamental element of any building. A corner-stone is also called a Quoins are the corner stones that anchor the edge of the building wall. Quoins may be structural, or may be decorative. Architects and builders use quoins to give the impression of strength and firmness to the outline of a building. A quoin is wedges, used to support or anchor other items.
