Remember Abraham, Isaac, and Israel, thy servants,.... The covenant he made with them, the promise he had made unto them, with an oath annexed to it:
to whom thou swarest by thine own self; which he did, because he could swear by no greater; and for the confirmation of his covenant and promise, see Genesis 22:16
and saidst unto them; for what was said to Abraham was repeated and confirmed to Isaac and Jacob:
I will multiply your seed as the stars of heaven; multitudes of which are out of sight, and cannot be seen with the naked eye, nor numbered:
and all this land that I have spoken of; the land of Canaan, then inhabited by several nations:
will I give unto your seed, and they shall inherit it for ever; as long as they are a people, a body politic, and especially while obedient to the divine will; but should they be now cut off, this promise would become of no effect: this is the great argument Moses makes use of, and the most forcible one.
