Exodus 16:32-34

32Moses said, “This is what the Lord has commanded: Take two quarts of manna to be kept for your descendants. This way they will see the food that I gave you to eat in the desert when I brought you out of Egypt.”

33Moses said to Aaron, “Take a jar, put two quarts of manna in it, and put it in the Lord’s presence to be kept for your descendants.”

34Aaron put the jar of manna in front of the words of God’s promise to be kept there, as the Lord commanded Moses.
