This is the thing which Yahweh has commanded: "Gather of it everyone according to his eating; an omer a head, according to the number of your persons, you shall take it, every man for those who are in his tent."

When they measured it with an omer, he who gathered much had nothing over, and he who gathered little had no lack. They gathered every man according to his eating.

It happened that on the sixth day they gathered twice as much bread, two omers for each one, and all the rulers of the congregation came and told Moses.

Moses said, "This is the thing which Yahweh has commanded, 'Let an omer-full of it be kept throughout your generations, that they may see the bread with which I fed you in the wilderness, when I brought you forth from the land of Egypt.'"

Moses said to Aaron, "Take a pot, and put an omer-full of manna in it, and lay it up before Yahweh, to be kept throughout your generations."

Now an omer is the tenth part of an ephah.
