Exodus 16:30-36

30So the people rested on the seventh day.

31The house of Israel called the bread manna; it was like coriander seed, white, and it tasted like flat pastry (wafers) made with honey.

32Then Moses said, “This is the word which the Lord commands, ‘Let an omer 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 out of the land of Egypt.’ ”

33So Moses said to Aaron, “Take a pot and put an omer of manna in it, and place it before the Lord to be kept throughout your generations.”

34As the Lord commanded Moses, so Aaron [eventually] placed it in the presence of the Testimony, to be kept.

35The Israelites ate manna forty years, until they reached an inhabited land; they ate the manna until they came to the border of the land of Canaan.

36(Now an omer is the tenth of an ephah.)
