Exodus 16:33-36

33Moses 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.”

34Aaron 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.

35So the people of Israel ate manna for forty years until they arrived at the land where they would settle. They ate manna until they came to the border of the land of Canaan.

36The container used to measure the manna was an omer, which was one-tenth of an ephah; it held about two quarts.
