Genesis 12:11-13

Darby Translation

¹¹ And it came to pass when he was come near to enter into Egypt, that he said to Sarai his wife, Behold now, I know that thou art a woman fair to look upon.

¹² And it will come to pass when the Egyptians see thee, that they will say, She is his wife; and they will slay me, and save thee alive.

¹³ Say, I pray thee, thou art my sister, that it may be well with me on thy account, and my soul may live because of thee.
