Genesis 26:24-25 (New King James Version)

²⁴ And the LORD appeared to him the same night and said, “I am the God of your father Abraham; do not fear, for I am with you. I will bless you and multiply your descendants for My servant Abraham’s sake.” ²⁵ So he built an altar there and called on the name of the LORD, and he pitched his tent there; and there Isaac’s servants dug a well.
