Genesis 26:23-25 - The Lord Appears To Isaac
23 And he went up thence to Beer-sheba. 24 And Jehovah appeared to him the same night, and said, I am the God of Abraham thy father: fear not, for I am with thee, and will bless thee, and multiply thy seed for my servant Abraham's sake.
25 And he built an altar there, and called upon the name of Jehovah. And he pitched his tent there; and there Isaac's servants dug a well.
