Ezekiel 4:2-3

and hast placed against it a siege, and builded against it a fortification, and poured out against it a mount, and placed against it camps, yea, set thou against it battering-rams round about.

And thou, take to thee an iron pan, and thou hast made it a wall of iron between thee and the city; and thou hast prepared thy face against it, and it hath been in a siege, yea, thou hast laid siege against it. A sign it is to the house of Israel.
