Ezekiel 4:1-3

1“Now you, son of man, 1get yourself a brick, place it before you, and inscribe a city on it--Jerusalem. 2Then 2lay siege against it, build a siege wall, pile up an assault ramp, set up camps, and place battering rams against it all around. 3Then get yourself an iron plate and set it up as an iron wall between yourself and the city, and direct your face toward it so that 3it is under siege, and besiege it. This will be a 4sign to the house of Israel.
