Genesis 26:23-25 - The Lord Appears To Isaac
23 He went from there to Beer-sheba. 24 That night Jehovah appeared to Isaac. Jehovah said: I am the God of your father Abraham. Do not be afraid, because I am with you. I will bless you and increase the number of your descendants for my servant Abraham's sake.
25 Isaac built an altar there and worshiped Jehovah. Then he set up his camp. His servants dug another well.
