Exodus 16:30-36

30So the people rested on the seventh day.

31The house of Israel called its name “manna.” It was like coriander seed and was white, and it tasted like wafers with honey.

32Moses said, “This is what the Lord has commanded: ‘Fill an omer with it to be kept for generations to come, so that they may see the food I fed you in the desert when I brought you out from the land of Egypt.’”

33Moses said to Aaron, “Take a jar and put in it an omer full of manna, and place it before the Lord to be kept for generations to come.”

34Just as the Lord commanded Moses, so Aaron placed it before the Testimony for safekeeping.

35Now the Israelites ate manna forty years, until they came to a land that was inhabited; they ate manna until they came to the border of the land of Canaan.

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