Deuteronomy 8
14 Ref then your heart be lifted up, and you forget Yahweh your God, who brought you forth out of the land of Egypt, out of the house of bondage;
15 Ref who led you through the great and terrible wilderness, [in which were] fiery serpents and scorpions, and thirsty ground where was no water; who brought you forth water out of the rock of flint;
16 Ref who fed you in the wilderness with manna, which your fathers didn't know; that he might humble you, and that he might prove you, to do you good at your latter end:
