Genesis 27:19-20, 24 NIV

Jacob said to his father, “I am Esau your firstborn. I have done as you told me. Please sit up and eat some of my game, so that you may give me your blessing.”

Isaac asked his son, “How did you find it so quickly, my son?” “The Lord your God gave me success,” he replied.

“Are you really my son Esau?” he asked. “I am,” he replied.
