Genesis 26:23-25 - The Lord Appears To Isaac
23 He went up from there to Beersheba. 24 The LORD appeared to him the same night, and said, "I am the God of Abraham your father. Do not be afraid, for I am with you, and will bless you, and multiply your seed for my servant Abraham's sake."
25 He built an altar there, and called on the name of the LORD, and pitched his tent there. There Isaac's servants dug a well.
