GENESIS 15:13-16 (KJV)

¹³And he said unto Abram, Know of a surety that thy seed shall be a stranger in a land that is not theirs, and shall serve them; and they shall afflict them four hundred years; ¹⁴And also that nation, whom they shall serve, will I judge: and afterward shall they come out with great substance. ¹⁵And thou shalt go to thy fathers in peace; thou shalt be buried in a good old age. ¹⁶But in the fourth generation they shall come hither again: for the iniquity of the Amori is not yet full.

GENESIS 16:7-16 (KJV)

⁷And the angel of YHVH found [Hagar] by a fountain of water in the wilderness, by the fountain in the way to Shur. ⁸And he said, Hagar, Sarai’s maid, whence camest thou? and whither wilt thou go? And she said, I flee from the face of my mistress Sarai. ⁹And the angel of YHVH said unto her, Return to thy mistress, and submit thyself under her hands. ¹⁰And the angel of YHVH said unto her, I will multiply thy seed exceedingly, that it shall not be numbered for multitude. ¹¹And the angel of YHVH said unto her, Behold, thou art with child, and shalt bear a son, and shalt call his name Yishmael; because YHVH hath heard thy affliction. ¹²And he will be a wild man; his hand will be against every man, and every man’s hand against him; and he shall dwell in the presence of all his brethren. ¹³And she called the name of YHVH that spake unto her, Thou God seest me: for she said, Have I also here looked after him that seeth me? ¹⁴Wherefore the well was called Be’er Lahai Ro’i; behold, it is between Qadesh and Bered. ¹⁵And Hagar bare Abram a son: and Abram called his son’s name, which Hagar bare, Ishmael. ¹⁶And Abram was fourscore and six years old, when Hagar bare Yishmael to Abram.

GENESIS 17:1-8, 15-21 (KJV)

¹And when Abram was ninety years old and nine, YHVH appeared to Abram, and said unto him, I am God Almighty; walk before me, and be thou perfect. ²And I will make my covenant between me and thee, and will multiply thee exceedingly. ³And Abram fell on his face: and God talked with him, saying, ⁴As for me, behold, my covenant is with thee, and thou shalt be a father of many nations. ⁵Neither shall thy name any more be called Abram, but thy name shall be Abraham; for a father of many nations have I made thee. ⁶And I will make thee exceeding fruitful, and I will make nations of thee, and kings shall come out of thee. ⁷And I will establish my covenant between me and thee and thy seed after thee in their generations for an everlasting covenant, to be a God unto thee, and to thy seed after thee. ⁸And I will give unto thee, and to thy seed after thee, the land wherein thou art a stranger, all the land of Kana’an, for an everlasting possession; and I will be their God.

¹⁵And God said unto Abraham, As for Sarai thy wife, thou shalt not call her name Sarai, but Sarah shall her name be. ¹⁶And I will bless her, and give thee a son also of her: yea, I will bless her, and she shall be a mother of nations; kings of people shall be of her. ¹⁷Then Abraham fell upon his face, and laughed, and said in his heart, Shall a child be born unto him that is an hundred years old? and shall Sarah, that is ninety years old, bear? ¹⁸And Abraham said unto God, O that Yishmael might live before thee! ¹⁹And God said, Sarah thy wife shall bear thee a son indeed; and thou shalt call his name Yitzhaq: and I will establish my covenant with him for an everlasting covenant, and with his seed after him. ²⁰And as for Yishmael, I have heard thee: Behold, I have blessed him, and will make him fruitful, and will multiply him exceedingly; twelve princes shall he beget, and I will make him a great nation. ²¹But my covenant will I establish with Yitzhaq, which Sarah shall bear unto thee at this set time in the next year.

GENESIS 18:10-15 (KJV)

¹⁰And he said, I will certainly return unto thee according to the time of life; and, lo, Sarah thy wife shall have a son. And Sarah heard it in the tent door, which was behind him. ¹¹Now Abraham and Sarah were old and well stricken in age; and it ceased to be with Sarah after the manner of women. ¹²Therefore Sarah laughed within herself, saying, After I am waxed old shall I have pleasure, my lord being old also? ¹³And YHVH said unto Abraham, Wherefore did Sarah laugh, saying, Shall I of a surety bear a child, which am old? ¹⁴Is any thing too hard for YHVH? At the time appointed I will return unto thee, according to the time of life, and Sarah shall have a son. ¹⁵Then Sarah denied, saying, I laughed not; for she was afraid. And he said, Nay; but thou didst laugh.

GENESIS 21:1-7, 12-13, 18 (KJV)

¹And YHVH visited Sarah as he had said, and YHVH did unto Sarah as he had spoken. ²For Sarah conceived, and bare Abraham a son in his old age, at the set time of which God had spoken to him. ³And Abraham called the name of his son that was born unto him, whom Sarah bare to him, Yitzhaq. ⁴And Abraham circumcised his son Yitzhaq being eight days old, as God had commanded him. ⁵And Abraham was an hundred years old, when his son Yitzhaq was born unto him. ⁶And Sarah said, God hath made me to laugh, so that all that hear will laugh with me. ⁷And she said, Who would have said unto Abraham, that Sarah should have given children suck? for I have born him a son in his old age.

¹²And God said unto Abraham, Let it not be grievous in thy sight because of the lad, and because of thy bondwoman; in all that Sarah hath said unto thee, hearken unto her voice; for in Yitzhaq shall thy seed be called. ¹³And also of the son of the bondwoman will I make a nation, because he is thy seed.

¹⁸Arise, lift up the lad, and hold him in thine hand; for I will make him a great nation.
