Deuteronomy 4:33

30 When you are in trouble and all these things have come on you, if, in the future, you are turned again to the Lord your God, and give ear to his voice:

31 Because the Lord your God is a God of mercy, he will not take away his help from you or let destruction overtake you, or be false to the agreement which he made by an oath with your fathers.

32 Give thought now to the days which are past, before your time, from the day when God first gave life to man on the earth, and searching from one end of heaven to the other, see if such a great thing as this has ever been, or if anything like it has been talked of in story.

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.
