Ezekiel 4:1-3

1“Now you, son of man, take a brick, set it in front of you, and draw the city of Jerusalem on it.

2Then lay siege against it: Construct a siege wall, build a ramp, pitch military camps, and place battering rams against it on all sides.

3Take an iron plate and set it up as an iron wall between yourself and the city. Face it so that it is under siege, and besiege it. This will be a sign for the house of Israel.
