You, human one, take a brick. Put it in front of you and draw the city of Jerusalem on it.
References for Ezekiel 4:1
Prepare the siege: Build a wall, construct ramps, set up army camps, and place battering rams all around.
Take an iron plate and set it up as an iron wall between you and the city. Face it directly. When it is under siege like this, press hard against it. This is a sign for the house of Israel.
