Ezekiel 4:1-3

KJ2000(i) 1 You also, son of man, take you a clay tablet, and lay it before you, and portray upon it the city, even Jerusalem: 2 And lay siege against it, and build a siege wall against it, and cast up a mound against it; set camps also against it, and place battering rams against it round about. 3 Moreover take unto you an iron plate, and set it for a wall of iron between you and the city: and set your face against it, and it shall be besieged, and you shall lay siege against it. This shall be a sign to the house of Israel.
