'Omer full' in the Bible

Moses said, "This is the thing which the LORD has commanded, 'Let an omer-full of it be kept throughout your generations, that they may see the bread with which I fed you in the wilderness, when I brought you forth from the land of Egypt.'"

Moses said to Aaron, "Take a pot, and put an omer-full of manna in it, and lay it up before the LORD, to be kept throughout your generations."
