Exodus 16:31-32

16:31 The house of Israel called its name “manna.” It was like coriander seed and was white, and it tasted like wafers with honey.

16:32 Moses 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.’”
