Genesis 27:19-20, 24

Jacob said to his father, “I am Esau your firstborn; I have done just as you told me; please arise, sit and eat of my game, that your soul may bless me.” But Isaac said to his son, “How is it that you have found it so quickly, my son?” And he said, “Because the LORD your God brought it to me.”

Then he said, “Are you really my son Esau?” He said, “I am.”
