Exodus 16:17

¹⁵And when the children of Israel saw it, they said one to another, What is this? for they knew not what it was; and Moses said to them,

¹⁶This is the bread which the Lord has given you to eat. This is that which the Lord has appointed: gather of it each man for his family, an omer for each person, according to the number of your souls, gather each of you with his fellow lodgers.

— Exodus 16:17 —

¹⁸And having measured the omer full, he that had gathered much had nothing over, and he that had gathered less had no lack; each gathered according to the need of those who belonged to him.

¹⁹And Moses said to them, Let no man leave of it till the morning.
