Exodus 16:19-21

Amplified Bible

¹⁹ Moses said, “Let none of it be left [overnight] until [the next] morning.” ²⁰ But they did not listen to Moses, and some left a supply of it until morning, and it bred worms and became foul and rotten; and Moses was angry with them. ²¹ So they gathered it every morning, each as much as he needed, because when the sun was hot it melted.
