And Isaac called Jacob, and blessed him, and charged him, and said unto him, Thou shalt not take a wife of the daughters of Canaan.

And Isaac called Jacob, and blessed him, and charged him, saying: Take not a wife of the stock of Chanaan:

And Isaac calleth unto Jacob, and blesseth him, and commandeth him, and saith to him, 'Thou dost not take a wife of the daughters of Caanan;

Then Isaac sent for Jacob, and blessing him, said, Do not take a wife from among the women of Canaan;

And so Isaac called for Jacob, and he blessed him, and he instructed him, saying: "Do not be willing to accept a mate from the family of Canaan.

Vocavit ergo Ishac Iahacob, et benedixit ei: praecepitque, et dixit ei, Non capies uxorem de filiabus Chenaan.

And Isaac called Jacob, and blessed him. It may be asked, whether the reason why Isaac repeats anew the benediction which he had before pronounced, was that the former one had been of no force; whereas, if he was a prophet and interpreter of the will of God, what had once proceeded from his mouth ought to have been firm and perpetual. I answer, although the benedictions was in itself efficacious, yet the faith of Jacob required support of this kind: just as the Lord, in reiterating, frequently the same promises, derogates nothing either from himself or from his word, but rather confirms the certainty of that word to his servants, lest, at any time, their confidence should be shaken through the infirmity of the flesh. What I have said must also be kept in mind, that Isaac prayed, not as a private person, but as one furnished with a special command of God, to transmit the covenant deposited with himself to his son Jacob. It was also of the greatest importance that now, at length, Jacob should be blessed by his father, knowingly and willingly; lest at a future time a doubt, arising from the recollection of his father's mistake and of his own fraud, might steal over his mind. Therefore Isaac, now purposely directing his words to his son Jacob, pronounces the blessing to be due to him by right, lest it should be thought that, having been before deceived, he had uttered words in vain, under a false character.

And Isaac called Jacob - See note on Genesis 27:46.
And blessed him - Now voluntarily and cheerfully confirmed to him the blessing, which he had before obtained through subtlety. It was necessary that he should have this confirmation previously to his departure; else, considering the way in which he had obtained both the birthright and the blessing, he might be doubtful, according to his own words, whether he might not have got a curse instead of a blessing. As the blessing now pronounced on Jacob was obtained without any deception on his part, it is likely that it produced a salutary effect upon his mind, might have led him to confession of his sin, and prepared his heart for those discoveries of God's goodness with which he was favored at Luz.

And Isaac called Jacob, and (a) blessed him, and charged him, and said unto him, Thou shalt not take a wife of the daughters of Canaan.
(a) This second blessing was to confirm Jacob's faith, lest he should think that his father had given it without God's leading.

And Isaac called Jacob,.... Or therefore (d), because of what Rebekah had said to him, related in the latter part of the preceding chapter, he sent for Jacob to come to him from his tent or apartment where he was, or from the field where he was keeping the flocks; thus paying a great regard to what his wife Rebekah had suggested to him, and which appeared to him very right and reasonable:
and blessed him; he did not send for him to chide and reprove him for his fraudulent dealings with him to get the blessing from his brother, much less to revoke it, but to confirm it; which was necessary to prevent doubts that might arise in the mind of Jacob about it, and to strengthen him against the temptations of Satan; since he was about to be sent away from his father's house solitary and destitute, to go into another country, where he was to be for awhile in a state of servitude; all which might seem to contradict the blessing and promises he had received, and would be a trial of his faith in them, as well as a chastisement on him for the fraudulent manner in which he obtained them:
and charged him, and said unto him, thou shall not take a wife of the daughters of Canaan; it was time that he was married; for he was now, as the Jewish writers (e) say, seventy seven, years of age, which exactly agrees with what Polyhistor (f), an Heathen writer, relates from Demetrius, that Jacob was seventy seven years of age when he came to Haran, and also his father Isaac was then one hundred and thirty seven years old; and so it is calculated by the best chronologers, and as he must be, since he was born when his father was sixty years of age; see Gill on Genesis 27:1; and being now declared the heir of the promised land, it was proper he should marry, but not with any of the Canaanites, who were to be dispossessed of the land of Canaan, and therefore their seed, and Abraham's, to whom it was given, must not be mixed. Isaac takes the same care, and gives the same charge concerning the marriage of his son Jacob, on whom the entail of the land was settled, as his father Abraham did concerning his, Genesis 24:3.

Jacob had blessings promised both as to this world and that which is to come; yet goes out to a hard service. This corrected him for the fraud on his father. The blessing shall be conferred on him, yet he shall smart for the indirect course taken to obtain it. Jacob is dismissed by his father with a solemn charge. He must not take a wife of the daughters of Canaan: those who profess religion, should not marry with those that care not for religion. Also with a solemn blessing. Isaac had before blessed him unwittingly; now he does it designedly. This blessing is more full than the former; it is a gospel blessing. This promise looks as high as heaven, of which Canaan was a type. That was the better country which Jacob and the other patriarchs had in view.

JACOB'S DEPARTURE. (Genesis. 28:1-19)
Isaac called Jacob and blessed him--He entered fully into Rebekah's feelings, and the burden of his parting counsel to his son was to avoid a marriage alliance with any but the Mesopotamian branch of the family. At the same time he gave him a solemn blessing--pronounced before unwittingly, now designedly, and with a cordial spirit. It is more explicitly and fully given, and Jacob was thus acknowledged "the heir of the promise."

Jacob's Departure from his Parents' House. - Rebekah's complaint reminded Isaac of his own call, and his consequent duty to provide for Jacob's marriage in a manner corresponding to the divine counsels of salvation.

Isaac blessed him, and charged him - Those that have the blessing must keep the charge annexed to it, and not think to separate what God has joined.
