Numbers 11:7-9

7The manna resembled coriander seed, and its appearance was like that of bdellium.

8The people walked around and gathered it. They ground it on a pair of grinding stones or crushed it in a mortar, then boiled it in a cooking pot and shaped it into cakes. It tasted like a pastry cooked with the finest oil.

9When the dew fell on the camp at night, the manna would fall with it.
