Exodus 16:13-21

13In the evening quail came up and covered the camp, and in the morning dew lay around the camp.

14And when the dew had gone up, there was on the face of the wilderness a fine, flake-like thing, fine as frost on the ground.

15When the people of Israel saw it, they said to one another, "What is it?" For they did not know what it was. And Moses said to them, "It is the bread that the Lord has given you to eat.

16This is what the Lord has commanded: 'Gather of it, each one of you, as much as he can eat. You shall each take an omer, according to the number of the persons that each of you has in his tent.'"

17And the people of Israel did so. They gathered, some more, some less.

18But when they measured it with an omer, whoever gathered much had nothing left over, and whoever gathered little had no lack. Each of them gathered as much as he could eat.

19And Moses said to them, "Let no one leave any of it over till the morning."

20But they did not listen to Moses. Some left part of it till the morning, and it bred worms and stank. And Moses was angry with them.

21Morning by morning they gathered it, each as much as he could eat; but when the sun grew hot, it melted.
