Exodus 16:18-20

Amplified Bible

¹⁸ When they measured it with an omer, he who had gathered a large amount had no excess, and he who had gathered little had no lack; every man gathered according to his need (family size). 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.
