Exodus 16:31-32

31And the house of Israel called its name Manna. And it was like white coriander seed, and the taste of it was like wafers made with honey.

32Then Moses said, “This is the thing which the Lord has commanded: ‘Fill an omer with it, to be kept for 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.’ ”
