Exodus 16:34-36

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