Genesis Chapter 21 Verse 2For Sarah conceived, and bare Abraham a son in his old age, at the set time of which God had spoken to him.

And Abimelech said unto Abraham, What sawest thou, that thou hast done this thing?

And Abraham said, Because I thought, Surely the fear of God [is] not in this place; and they will slay me for my wife's sake.

And yet indeed [she is] my sister; she [is] the daughter of my father, but not the daughter of my mother; and she became my wife.

And it came to pass, when God caused me to wander from my father's house, that I said unto her, This [is] thy kindness which thou shalt shew unto me; at every place whither we shall come, say of me, He [is] my brother.

And Abimelech took sheep, and oxen, and menservants, and womenservants, and gave [them] unto Abraham, and restored him Sarah his wife.

And Abimelech said, Behold, my land [is] before thee: dwell where it pleaseth thee.

And unto Sarah he said, Behold, I have given thy brother a thousand [pieces] of silver: behold, he [is] to thee a covering of the eyes, unto all that [are] with thee, and with all [other]: thus she was reproved.

So Abraham prayed unto God: and God healed Abimelech, and his wife, and his maidservants; and they bare [children].

For the LORD had fast closed up all the wombs of the house of Abimelech, because of Sarah Abraham's wife.

And the LORD visited Sarah as he had said, and the LORD did unto Sarah as he had spoken.

And Abraham called the name of his son that was born unto him, whom Sarah bare to him, Isaac.

And Abraham circumcised his son Isaac being eight days old, as God had commanded him.

And Abraham was an hundred years old, when his son Isaac was born unto him.

And Sarah said, God hath made me to laugh, [so that] all that hear will laugh with me.

And 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.

And the child grew, and was weaned: and Abraham made a great feast the [same] day that Isaac was weaned.

And Sarah saw the son of Hagar the Egyptian, which she had born unto Abraham, mocking.

Wherefore she said unto Abraham, Cast out this bondwoman and her son: for the son of this bondwoman shall not be heir with my son, [even] with Isaac.

And the thing was very grievous in Abraham's sight because of his son.

And 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 Isaac shall thy seed be called.
