Exodus 16:31-32

31The Israelites called the special food ‘manna’. It was white, like seeds called coriander. When they tasted the manna, it was like thin pieces of bread with honey in it.

32Moses said, ‘This is what the Lord has commanded: “Keep one bowl (an omer) of manna for people to look at in future times. They will see the bread that I fed to you in the desert, after I had brought you out of Egypt.” ’
