Deuteronomy 4:36

33 Has any people ever gone on living after hearing the voice of God out of the heart of the fire as you did?

34 Has God ever before taken a nation for himself from out of another nation, by punishments and signs and wonders, by war and by a strong hand and a stretched-out arm and great acts of wonder and fear, as the Lord your God did for you in Egypt, before your very eyes?

35 All this he let you see, so that you might be certain that the Lord is God and there is no other.

36 Out of heaven itself his voice came to you, teaching you; and on earth he let you see his great fire; and his words came to your ears out of the heart of the fire.

37 And because of his love for your fathers, he took their seed and made it his, and he himself, present among you, took you out of Egypt by his great power;

38 Driving out before you nations greater and stronger than you, to take you into their land and give it to you for your heritage, as at this day.

39 So today be certain, and keep the knowledge deep in your hearts, that the Lord is God, in heaven on high and here on earth; there is no other God.
