Ezekiel 4:1-3

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