Exodus 16:30-33
English Standard Version
Chapter 16
30So the people rested on the seventh day.
31Now the house of Israel called its name manna. It was like coriander seed, white, and the taste of it was like wafers made with honey.
32Moses said, "This is what the Lord has commanded: ‘Let an omer of it be kept throughout your generations, so that they may see the bread with which I fed you in the wilderness, when I brought you out of the land of Egypt.’"
33And 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."
