Genesis 27:19-20, 24

Jacob said to his father, “I am Esau your firstborn. I have done as you told me; now sit up 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?” He answered, “Because the LORD your God granted me success.”

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