Exodus 16:18-20

International Standard Version

¹⁸ When they measured it with a vessel the capacity of which was one omer,^[a] the one who gathered much did not have an excess, while the one who gathered little did not lack. They gathered exactly what each needed to eat.^[b]

¹⁹ Then Moses told them, “No one is to leave any of it until morning.” ²⁰ But they did not listen to Moses—some people left part of it until morning, and it produced maggots and smelled bad, so Moses got angry at them.
