Ezekiel 4:1-5

Thou also, son of man, take thee a tile, and lay it before thee, and portray upon it a city, even Jerusalem: and lay siege against it, and build forts against it, and cast up a mound against it; set camps also against it, and plant battering rams against it round about. And take thou unto thee an iron pan, and set it for a wall of iron between thee and the city: and set thy face toward it, and it shall be besieged, and thou shalt lay siege against it. This shall be a sign to the house of Israel. Moreover lie thou upon thy left side, and lay the iniquity of the house of Israel upon it; according to the number of the days that thou shalt lie upon it, thou shalt bear their iniquity. For I have appointed the years of their iniquity to be unto thee a number of days, even three hundred and ninety days: so shalt thou bear the iniquity of the house of Israel.
