Exodus 16:31-35 NRSV
The house of Israel called it manna; it was like coriander seed, white, and the taste of it was like wafers made with honey. Moses said, “This is what the LORD has commanded: ‘Let an omer of it be kept throughout your generations, in order that they may see the food with which I fed you in the wilderness, when I brought you out of the land of Egypt.’ ” And Moses said to Aaron, “Take a jar, and put an omer of manna in it, and place it before the LORD, to be kept throughout your generations.” As the LORD commanded Moses, so Aaron placed it before the covenant, for safekeeping. The Israelites ate manna forty years, until they came to a habitable land; they ate manna, until they came to the border of the land of Canaan.
