Genesis 12:11; Genesis 12:13; Genesis 18:4; Genesis 18:30
And it came to pass, when he was come near to enter into Egypt, that he said unto Sarai his wife, Behold now, I know that thou art a fair woman to look upon:
Say, I pray thee, thou art my sister: that it may be well with me for thy sake; and my soul shall live because of thee.
Let a little water, I pray you, be fetched, and wash your feet, and rest yourselves under the tree:
And he said unto him, Oh let not the Lord be angry, and I will speak: Peradventure there shall thirty be found there. And he said, I will not do it, if I find thirty there.
