Genesis 27:19

And Jacob said unto his father, I am Esau, thy first-born; I have done according as thou badest me; arise, I pray thee, sit and eat of my venison, that thy soul may bless me. Jacob here became guilty of his mother's deceit in deed as well as in words and intent, for he was not Esau, nor was the meat which he was bringing venison. So far as he was concerned, he was trying to obtain his father's blessing under false pretenses.
