THE COVENANT AT MOUNT SINAI WAS MADE WITH THOSE WHO WERE THERE AND THOSE WHO WERE NOT THERE

Deuteronomy 29:12 That thou shouldest enter into covenant with the LORD thy God, and into his oath, which the LORD thy God maketh with thee this day:

Deuteronomy 29:13 That he may establish thee to day for a people unto himself, and that he may be unto thee a God, as he hath said unto thee, and as he hath sworn unto thy fathers, to Abraham, to Isaac, and to Jacob.
