Deuteronomy 8:14-16

New Catholic Bible

¹⁴ then your heart might become proud and you will forget the Lord, your God, who brought you out of the land of Egypt, the land of your slavery. ¹⁵ He led you through a vast and terrible wilderness where there were snakes and fiery scorpions and thirst, where when there was no water he brought water forth from the hard rock for you. ¹⁶ He gave you manna to eat in the wilderness, something with which your fathers were not familiar, to abase you and to test you, so that later on it might go well with you.
