Deuteronomy 8:13-20

13 and thy herd and thy flock be multiplied, and silver and gold be multiplied to thee; and all that is thine be multiplied:
14 `And thy heart hath been high, and thou hast forgotten Jehovah thy God (who is bringing thee out of the land of Egypt, out of a house of servants;
15 who is causing thee to go in the great and the terrible wilderness -- burning serpent, and scorpion, and thirst -- where there is no water; who is bringing out to thee waters from the flinty rock;
16 who is causing thee to eat manna in the wilderness, which thy fathers have not known, in order to humble thee, and in order to try thee, to do thee good in thy latter end),
17 and thou hast said in thy heart, My power, and the might of my hand, hath made for me this wealth:
18 `And thou hast remembered Jehovah thy God, for He it [is] who is giving to thee power to make wealth, in order to establish His covenant which He hath sworn to thy fathers as [at] this day.
19 `And it hath been -- if thou really forget Jehovah thy God, and hast gone after other gods, and served them, and bowed thyself to them, I have testified against you to-day that ye do utterly perish;
20 as the nations whom Jehovah is destroying from your presence, so ye perish; because ye hearken not to the voice of Jehovah your God.
