Numbers 11:7-9
11:7 (Now the manna was like coriander seed, and its color like the color of bdellium.
11:8 And the people went about and gathered it, and ground it with mills or pounded it in mortars; they baked it in pans and made cakes of it. It tasted like fresh olive oil.
11:9 And when the dew came down on the camp in the night, the manna fell with it.)
