Exodus 16:31-36

31The house of Israel named it manna . It was white like coriander seed and tasted like wafers made with honey.

32Then Moses said, “This is what Adonai has commanded. Let a full omer of it be kept throughout your generations, so that they may see the bread with which I fed you in the wilderness, when I brought you out from the land of Egypt.”

33Moses said to Aaron, “Take a jar and put a full omer of manna inside. Store it up before Adonai, to be kept throughout your generations.”

34Just as Adonai commanded Moses, Aaron stored it up in front of the Testimony, to be preserved.

35Bnei-Yisrael ate the manna for 40 years. They ate the manna until they came to an inhabited land, when they came to the borders of the land of Canaan.

36Now an omer is the tenth part of an ephah.
