Exodus 16:31-32

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