Deuteronomy 8:16 in the King James Version
Who fed thee in the wilderness with manna, which thy fathers knew not, that he might humble thee, and that he might prove thee, to do thee good at thy latter end;
Context
15 who led you through the great and terrible wilderness, with venomous snakes and scorpions, and thirsty ground where there was no water; who poured water for you out of the rock of flint;
16 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;
17 and lest you say in your heart, “My power and the might of my hand has gotten me this wealth.”
