Genesis 27:19-24

Jacob said to him, “I am Esau, your first son. I have done what you told me. Now sit up and eat some meat of the animal I hunted for you. Then bless me.” But Isaac asked his son, “How did you find and kill the animal so quickly?” Jacob answered, “Because the LORD your God helped me to find it.” Then Isaac said to Jacob, “Come near so I can touch you, my son. Then I will know if you are really my son Esau.” So Jacob came near to Isaac his father. Isaac touched him and said, “Your voice sounds like Jacob’s voice, but your hands are hairy like the hands of Esau.” Isaac did not know it was Jacob, because his hands were hairy like Esau’s hands, so Isaac blessed him. Isaac asked, “Are you really my son Esau?” Jacob answered, “Yes, I am.”
