Deuteronomy 8:15-16

Leeser(i) 15 Who hath led thee through the great and terrible wilderness, wherein are snakes, poisonous serpents, and scorpions, and drought, where there is no water; who hath brought forth for thee water out of the flinty rock; 16 Who hath fed thee in the wilderness with manna, which thy fathers knew not; in order to afflict thee, and in order to prove thee, to do thee good at thy latter end;
