Exodus 16:16-21

16“This is what the Lord has commanded: ‘Each person is to gather from it what he can eat, an omer per person according to the number of your people; each one will pick it up for whoever lives in his tent.’”

17The Israelites did so, and they gathered – some more, some less.

18When they measured with an omer, the one who gathered much had nothing left over, and the one who gathered little lacked nothing; each one had gathered what he could eat.

19Moses said to them, “No one is to keep any of it until morning.”

20But they did not listen to Moses; some kept part of it until morning, and it was full of worms and began to stink, and Moses was angry with them.

21So they gathered it each morning, each person according to what he could eat, and when the sun got hot, it would melt.
