Exodus 16:19

¹⁷And the children of Israel did so, and gathered some much and some less.

¹⁸And having measured the omer full, he that had gathered much had nothing over, and he that had gathered less had no lack; each gathered according to the need of those who belonged to him.

— Exodus 16:19 —

²⁰But they did not hearken to Moses, but some left of it till the morning; and it bred worms and stank: and Moses was irritated with them.

²¹And they gathered it every morning, each man what he needed, and when the sun waxed hot it melted.
