Deuteronomy 4:33-35

33Did [ever] people hear the voice of 1God speaking from the midst of the fire, as thou hast heard, and live?

34Or hath 2God essayed to come to take him a nation from the midst of a nation, by trials, by signs, and by wonders, and by war, and by a powerful hand, and by a stretched-out arm, and by great terrors, according to all that Jehovah your 3God did for you in Egypt before your eyes?

35Unto thee it was shewn, that thou mightest know that Jehovah, he is 4God — there is none other besides him.
