Exodus 16:32-34

Then Moses said, “This is what the LORD has commanded: Fill a two-quart container with manna to preserve it for your descendants. Then later generations will be able to see the food I gave you in the wilderness when I set you free from Egypt.” Moses said to Aaron, “Get a jar and fill it with two quarts of manna. Then put it in a sacred place before the LORD to preserve it for all future generations.” Aaron did just as the LORD had commanded Moses. He eventually placed it in the Ark of the Covenant—in front of the stone tablets inscribed with the terms of the covenant.
