(19) Arise . . . sit and eat.--The Hebrews at this time, and for centuries, sat at their meals (1Samuel 20:25). It was from the Romans that they learned to recline at table, as we find was their custom in the Gospels. It is a mistake, moreover, to suppose that Isaac was a bedridden old man, for Jacob bids him arise and seat himself. Nor does he help him, though his sight was weak. It is only when commanded to draw near that he lets his father touch him.

Verse 19. - And Jacob (either not observing or not regarding the trepidation which his voice caned, but being well schooled by his crafty mother, and determined to go through with what perhaps he esteemed a perfectly justifiable transaction) said unto his father, I am Esau thy firstborn. A reply for which laborious excuses have been invented; as that Jacob spoke mystically, meaning not that he individually, but that his descendants, the Church, were Isaac's firstborn (Augustine); or figuratively, as importing that since he had already bought Esau s birthright, he might justly regard himself as standing in Esau's place (Theodoret, Aquinas). It is better not to attempt vindication of conduct which to ordinary minds must ever appear questionable, but rather to hold that "Jacob told an officious lie to his father" (Willet). I have done according as thou badest me. If the former assertion might be cleared of mendacity, it is difficult to see how this can. By no conceivable sophistry could he convince his conscience that he was acting in obedience to his father, while he was knowingly implementing the instructions of his mother. This was Jacob's second lie. - Arise, I pray thee, sit and eat of my venison. Lie three. One lie commonly requires another to support or conceal it. Few who enter on a course of deception stop at one falsehood. That thy soul may bless me. It was the blessing of the Abrahamic covenant he craved.

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.And Jacob said unto his father, I am Esau thy firstborn,.... Had he only said that he was his firstborn, he might have been excused from lying, because he had bought the birthright of Esau; but when he says, I am Esau, he can by no means be excused; for to say he impersonated Esau will not do; besides, he afterwards says he was his very son Esau, Genesis 27:24,

I have done according as thou badest me; which is another lie; for Isaac had not bid him bring him any venison, nor go into the field for it, and take it and dress it for him; nor indeed had Jacob done either of these:

arise, I pray thee, sit and eat of my venison; or "hunting" (u), what he had hunted; another untruth, for it was not venison he brought him, nor anything that was hunted by him: by this it seems that Isaac lay upon a bed or couch through infirmity, and therefore is bid to arise and put himself in a proper posture for eating, which in those times and countries was usually sitting:

that thy soul may bless me; as this was the thing in view, so speaking of it as soon as he came in, and which he desired might be done after his father had eat and drank, might serve to take off the suspicion of his being another person; since this was what Isaac himself proposed to Esau to do; and this he said when there were none else present.
