Exodus 16:18-20

Revised Standard Version

¹⁸ But when they measured it with an omer, he that gathered much had nothing over, and he that gathered little had no lack; each gathered according to what he could eat. ¹⁹ And Moses said to them, “Let no man leave any of it till the morning.” ²⁰ But they did not listen to Moses; some left part of it till the morning, and it bred worms and became foul; and Moses was angry with them.
