Genesis 26:23-25

26:23 From there Isaac went up to Beer Sheba. 26:24 The Lord appeared to him that night and said, “I am the God of your father Abraham. Do not be afraid, for I am with you. I will bless you and multiply your descendants for the sake of my servant Abraham.” 26:25 Then Isaac built an altar there and worshiped the Lord. He pitched his tent there, and his servants dug a well.
