On the sixth day they gathered twice as much bread, two omers each. And when all the leaders of the congregation came and told Moses,

Moses said, "This is what the LORD has commanded: 'Let an omer of it be kept throughout your generations, so that they may see the bread with which I fed you in the wilderness, when I brought you out of the land of Egypt.'" And Moses said to Aaron, "Take a jar, and put an omer of manna in it, and place it before the LORD to be kept throughout your generations."

(An omer is the tenth part of an ephah.)
