Deuteronomy 4:30-40

30 When you are in oppression, and all these things are come on you, in the latter days you shall return to the LORD your God, and listen to his voice:
31 for the LORD your God is a merciful God; he will not fail you, neither destroy you, nor forget the covenant of your fathers which he swore to them.
32 For ask now of the days that are past, which were before you, since the day that God created man on the eretz, and from the one end of the sky to the other, whether there has been [any such thing] as this great thing is, or has been heard like it?
33 Did ever a people hear the voice of God speaking out of the midst of the fire, as you have heard, and live?
34 Or has God tried to go and take him a nation from the midst of [another] nation, by trials, by signs, and by wonders, and by war, and by a mighty hand, and by an outstretched arm, and by great terrors, according to all that the LORD your God did for you in Mitzrayim before your eyes?
35 To you it was shown, that you might know that the LORD he is God; there is none else besides him.
36 Out of heaven he made you to hear his voice, that he might instruct you: and on eretz he made you to see his great fire; and you heard his words out of the midst of the fire.
37 Because he loved your fathers, therefore he chose their seed after them, and brought you out with his presence, with his great power, out of Mitzrayim;
38 to drive out nations from before you greater and mightier than you, to bring you in, to give you their land for an inheritance, as at this day.
39 Know therefore this day, and lay it to your heart, that the LORD he is God in heaven above and on the eretz beneath; there is none else.
40 You shall keep his statutes, and his mitzvot, which I command you this day, that it may go well with you, and with your children after you, and that you may prolong your days in the land, which the LORD your God gives you, forever.
