Numbers 11:4-9

Then the foreign rabble who were traveling with the Israelites began to crave the good things of Egypt. And the people of Israel also began to complain. “Oh, for some meat!” they exclaimed. “We remember the fish we used to eat for free in Egypt. And we had all the cucumbers, melons, leeks, onions, and garlic we wanted. But now our appetites are gone. All we ever see is this manna!” The manna looked like small coriander seeds, and it was pale yellow like gum resin. The people would go out and gather it from the ground. They made flour by grinding it with hand mills or pounding it in mortars. Then they boiled it in a pot and made it into flat cakes. These cakes tasted like pastries baked with olive oil. The manna came down on the camp with the dew during the night.
