The Lord made not this covenant with our fathers That is, with our remote progenitors, with Abraham, Isaac, and Jacob, but with us, their descendants: or if it be understood as spoken of their immediate parents, it means, according to the Hebrew idiom, Not with our fathers only, but with us also, as Genesis 32:28, Thy name shall be called no more Jacob, but Israel; that is, not only Jacob, but Israel, or Israel preferably to Jacob. Moses might truly say, God made this covenant with them then present before him; for a great part of them, even all who were under twenty years of age, when God gave the law on mount Sinai, were at Horeb; and, as God foreknew that their parents would die in the wilderness for their unbelief and murmuring, and would have comparatively little profit from that covenant, he especially intended it for those who should enter Canaan, and who, with their posterity, should be governed and benefited by it from generation to generation.
