Exodus 16:19-21

New Catholic Bible

¹⁹ Then Moses said to them, “Nothing should be left till the morning.” ²⁰ However, some did not obey Moses and saved a bit of it until the morning, but it grew rancid and had worms. Moses was angry with them.

²¹ They therefore collected it each morning, as much as each one would eat. When the sun warmed up, it melted away.
