And confirmed the same unto Jacob for a law, and to Israel for an everlasting covenant:

And he appointed the same to Jacob for a law, and to Israel for an everlasting testament:

And doth establish it to Jacob for a statute, To Israel, a covenant age-during,

And he gave it to Jacob for a law, and to Israel for an eternal agreement;

And He established it unto Jacob for a statute, To Israel for an everlasting covenant;

And confirmed the same unto Jacob - literally, "caused it to stand;" that is, he made it fast or secure. He renewed it, commanding the same things; making the same promises; and pledging himself for its fulfillment in the same manner. Genesis 28:10-15.
For a law - For an established or settled ordinance, for a rule by which future things were to be regulated: that is, they would occur according to that promise, and be conformed to it. It was, as it were, a rule which God prescribed for himself in regard to his own future conduct.
And to Israel - Another name for Jacob, Genesis 32:28.

And confirmed the same unto Jacob for a law,.... The son of Isaac, and the grandson of Abraham, to whom it was renewed and confirmed, Genesis 28:13. It is true of his posterity that go by his name, and even of all the spiritual Israel of God, to whom this covenant is confirmed and made sure: or "caused to stand" (b), as the word is; by the faithfulness of God by his oath annexed to his word, and by the death of his Son: when this is said to be "for a law", the meaning is, not as if this covenant had the nature of a law, as the covenant of works had; indeed one of the articles of it is, that the law of God should be put into the inward part, and written on the heart; but this refers here not to men, but to God; and the sense is, that this covenant has the force of a law with respect to God, who of his condescending grace and goodness has hereby laid himself under obligation to do such and such things; which is marvellous grace indeed.
And to Israel for an everlasting covenant: for being remembered, commanded, repeated, and confirmed by the Lord, it can never be broken; and being well ordered, remains sure, and is as immovable as rocks and mountains, and more so: as it was made with Christ from everlasting, it will continue to be made good to his people to everlasting; and is a just reason for praise; it being the basis of faith and hope; the ground of joy, peace, and comfort here, and of eternal happiness hereafter.
(b) "stare fecit", Vatablus.

Alluding to God's promise to Jacob (Genesis 28:13). Out of the whole storehouse of the promises of God, only one is prominently brought forward, namely, that concerning the possession of Canaan [Psalm 105:11]. Everything revolves around this. The wonders and judgments have all for their ultimate design the fulfilment of this promise.

A law - That it might be as firm and irrevocable as a law.
