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.This is what the LORD has commanded: ‘Each one is to gather as much as he needs. You may take an omer for each person in your tent.’”
Exodus 16:32-33
³² And Moses said, This is the thing which the Lord commandeth, Fill an omer of it to be kept for your generations; that they may see the bread wherewith I have fed you in the wilderness, when I brought you forth from the land of Egypt. ³³ And Moses said unto Aaron, Take a pot, and put an omer full of manna therein, and lay it up before the Lord, to be kept for your generations.³² Moses said, “This is what the LORD has commanded: ‘Keep an omer of manna for the generations to come, so that they may see the bread I fed you in the wilderness when I brought you out of the land of Egypt.’” ³³ So Moses told Aaron, “Take a jar and fill it with an omer of manna. Then place it before the LORD to be preserved for the generations to come.”
