Exodus 16:19 WEB

¹⁷  The children of Israel did so, and gathered some more, some less.

¹⁸  When they measured it with an omer, he who gathered much had nothing over, and he who gathered little had no lack. They gathered every man according to his eating.

¹⁹  Moses said to them, 'Let no one leave of it until the morning.'

²⁰  Notwithstanding they didn't listen to Moses, but some of them left of it until the morning, and it bred worms, and became foul: and Moses was angry with them.

²¹  They gathered it morning by morning, everyone according to his eating. When the sun grew hot, it melted.
