Genesis Chapter 20
Abraham sojourned in Gerara: Sara is taken into king Abimelech's house, but by God's commandment is restored untouched.
20:1. Abraham removed from thence to the south country, and dwelt between Cades and Sur, and sojourned in Gerara.
20:2. And he said of Sara his wife: She is my sister. So Abimelech the king of Gerara sent, and took her.
20:3. And God came to Abimelech in a dream by night, and he said to him: Lo thou shalt die for the woman that thou hast taken: for she hath a husband.
20:4. Now Abimelech had not touched her, and he said: Lord, wilt thou slay a nation that is ignorant and just?
20:5. Did not he say to me: She is my sister: and she say, He is my brother? in the simplicity of my heart, and cleanness of my hands have I done this.
