Exodus 16:15-17

King James Version

¹⁵ And when the children of Israel saw it, they said one to another, It is manna: for they wist not what it was. And Moses said unto them, This is the bread which the Lord hath given you to eat.

¹⁶ This is the thing which the Lord hath commanded, Gather of it every man according to his eating, an omer for every man, according to the number of your persons; take ye every man for them which are in his tents.

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