14 when your heart is lifted up, and you forget the Lord your God who brought you out of the land of Egypt, from the house of bondage;

15 who led you through that great and terrible wilderness, in which were fiery serpents and scorpions and thirsty land where there was no water; who brought water for you out of the flinty rock;

16 who fed you in the wilderness with manna, which your fathers did not know, that He might humble you and that He might test you, to do you good in the end--
