Exodus 16:16-21

16This is the thing which Jehovah has commanded: Gather of it every man according to what he can eat, an omer a poll, [according to] the number of your persons: ye shall take every man for those that are in his tent.

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

18And they measured with the omer: then he that gathered much had nothing over, and he that gathered little wanted nothing: they had gathered every man according to the measure of his eating.

19And Moses said to them, Let no man leave [any] of it until the morning.

20But they did not hearken to Moses; and some men left of it until the morning; then worms bred in it and it stank. And Moses was wroth with them.

21And they gathered it every morning, every man as much as he could eat; and when the sun became hot, it melted.
