Genesis 26:23-25

And he went up from thence to Beer-sheba. And Jehovah appeared unto 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. And he builded an altar there, and called upon the name of Jehovah, and pitched his tent there: and there Isaac’s servants digged a well.
