Exodus 16:32

“And Moses said, etc.] At another time, though it is here inserted to give the account of the mamma all together: this is the thing which the Lord commandeth; namely, what follows: fill an omer of it to be kept for your generations; which was the quantity allowed a man every day; this measure was to be laid up, and reserved for posterity in future generations, not to eat, nor so much as taste of, for then it would soon have been gone, but to look at, as follows: that they may see the bread wherewith I have fed you in the wilderness, when I brought you out of the land of Egypt; that they might see what sort of food was provided for them, and what quantity each man had of it every day; and so…”
