Exodus 16:18, 33, 36

But when they measured it out, everyone had just enough. Those who gathered a lot had nothing left over, and those who gathered only a little had enough. Each family had just what it needed.

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.”

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