Genesis Chapter 20 Verse 12And 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 Abraham said of Sarah his wife, She [is] my sister: and Abimelech king of Gerar sent, and took Sarah.

But God came to Abimelech in a dream by night, and said to him, Behold, thou [art but] a dead man, for the woman which thou hast taken; for she [is] a man's wife.

But Abimelech had not come near her: and he said, Lord, wilt thou slay also a righteous nation?

Said he not unto me, She [is] my sister? and she, even she herself said, He [is] my brother: in the integrity of my heart and innocency of my hands have I done this.

And God said unto him in a dream, Yea, I know that thou didst this in the integrity of thy heart; for I also withheld thee from sinning against me: therefore suffered I thee not to touch her.

Now therefore restore the man [his] wife; for he [is] a prophet, and he shall pray for thee, and thou shalt live: and if thou restore [her] not, know thou that thou shalt surely die, thou, and all that [are] thine.

Therefore Abimelech rose early in the morning, and called all his servants, and told all these things in their ears: and the men were sore afraid.

Then Abimelech called Abraham, and said unto him, What hast thou done unto us? and what have I offended thee, that thou hast brought on me and on my kingdom a great sin? thou hast done deeds unto me that ought not to be done.

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 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.

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

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.
