27:19 And Jacob said unto his father, {d} I [am] Esau thy firstborn; I have done according as thou badest me: arise, I pray thee, sit and eat of my venison, that thy soul may bless me.
(d) Although Jacob was assured of this blessing by faith: yet he did evil to seek it by lies, even more because he abuses God's name through it.
27:19 And Jacob said, I am Esau - Who would have thought this plain man could have played such a part? His mother having put him in the way of it, he applies himself to those methods which he had never accustomed himself to, but had always conceived an abhorrence of. But lying is soon learned. I wonder how honest Jacob could so readily turn his tongue to say, I am Esau thy first - born: and when his father asked him, Ge 27:24. Art thou my very son Esau? to reply I am. How could he say, I have done as thou badst me, when he had received no command from his father, but was doing as his mother bid him? How could he say, Eat of my venison, when he knew it came not from the field, but from the fold? But especially I wonder how he could have the forehead to father it upon God, and to use his name in the cheat.
27:18-29 Jacob, with some difficulty, gained his point, and got the blessing. This blessing is in very general terms. No mention is made of the distinguishing mercies in the covenant with Abraham. This might be owing to Isaac having Esau in his mind, though it was Jacob who was before him. He could not be ignorant how Esau had despised the best things. Moreover, his attachment to Esau, so as to disregard the mind of God, must have greatly weakened his own faith in these things. It might therefore be expected, that leanness would attend his blessing, agreeing with the state of his mind.
