Ezekiel 4:11

9“Take for yourself also wheat, barley, beans, lentils, millet, and spelt, and put them in one vessel. Make bread of it. According to the number of the days that you will lie on your side, even three hundred ninety days, you shall eat of it.

10Your food which you shall eat shall be by weight, twenty shekels a day. From time to time you shall eat it.

11You shall drink water by measure, the sixth part of a hin. From time to time you shall drink.

12You shall eat it as barley cakes, and you shall bake it in their sight with dung that comes out of man.”

13The LORD said, “Even thus will the children of Israel eat their bread unclean, among the nations where I will drive them.”
