Exodus 16:16-18

16This is the thing which the Lord has commanded: ‘Let every man gather it according to each one’s need, one omer for each person, according to the number of persons; let every man take for those who are in his tent.’ ”

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

18So when they measured it by omers, he who gathered much had nothing left over, and he who gathered little had no lack. Every man had gathered according to each one’s need.
