Exodus 16:32-33

Webster(i) 32 And Moses said, This is the thing which the LORD commanded, Fill an omer of it to be kept for your generations; that they may see the bread with which I fed you in the wilderness, when I brought you forth from the land of Egypt. 33 And Moses said to Aaron, Take a pot, and put an omer full of manna therein, and lay it up before the LORD, to be kept for your generations.
