Ezekiel 4:9-10

9Take thou also unto thee wheat, and barley, and beans, and lentils, and millet, and spelt, and put them in one vessel, and make thee bread thereof; according to the number of the days that thou shalt lie upon thy side, even three hundred and ninety days, shalt thou eat thereof. 10And thy food which thou shalt eat shall be by weight, twenty shekels a day: from time to time shalt thou eat it.
