Ezequiel 4:3

3 E tu toma uma sertã de ferro, e põe-na por muro de ferro entre ti e a cidade; e dirige para ela o teu rosto, e assim será cercada, e a cercarás; isto servirá de sinal à casa de Israel.

3 And take a flat iron plate, and put it for a wall of iron between you and the town: and let your face be turned to it, and it will be shut in and you will make an attack on it. This will be a sign to the children of Israel.
