Genesis Chapter 20 Verse 5Said 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 they made their father drink wine that night: and the firstborn went in, and lay with her father; and he perceived not when she lay down, nor when she arose.

And it came to pass on the morrow, that the firstborn said unto the younger, Behold, I lay yesternight with my father: let us make him drink wine this night also; and go thou in, [and] lie with him, that we may preserve seed of our father.

And they made their father drink wine that night also: and the younger arose, and lay with him; and he perceived not when she lay down, nor when she arose.

Thus were both the daughters of Lot with child by their father.

And the firstborn bare a son, and called his name Moab: the same [is] the father of the Moabites unto this day.

And the younger, she also bare a son, and called his name Benammi: the same [is] the father of the children of Ammon unto this day.

And Abraham journeyed from thence toward the south country, and dwelled between Kadesh and Shur, and sojourned in Gerar.

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?

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 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.
