Deuteronomy 29:13-17

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.

Neither with you only do I make this covenant and this oath;

But with him that standeth here with us this day before the LORD our God, and also with him that is not here with us this day:

(For ye know how we have dwelt in the land of Egypt; and how we came through the nations which ye passed by;

And ye have seen their abominations, and their idols, wood and stone, silver and gold, which were among them:)
