Exodus 16:32-34

And Moses said, This is the thing which Jehovah hath commanded, Let an omerful of it be kept throughout your generations, that they may see the bread wherewith I fed you in the wilderness, when I brought you forth from the land of Egypt. And Moses said unto Aaron, Take a pot, and put an omerful of manna therein, and lay it up before Jehovah, to be kept throughout your generations. As Jehovah commanded Moses, so Aaron laid it up before the Testimony, to be kept.
