Then Moses said, “The Lord said, ‘Save two quarts of this food for your descendants. Then they can see the food I gave you to eat in the desert when I brought you out of Egypt.’ ”
and manna to eat in the desert. Manna was something your ancestors had never seen. He did this to take away your pride and to test you, so things would go well for you in the end.
