Ezekiel's Vision of the City of Jerusalem

Ezekiel is told to cook his food over human poop and then as a says or Ezekiel says please I don't want to eat anything unclean and God says okay fine over cow poop that's fine over manure you can do that. Then he has the other image that's the one image of the army men in the siege works against Jerusalem reenacting this but then also the sharp sword so Ezekiel is told to cut off his hair and cut off his beard with a sword which is not what people would use to cut hair typically but it's a sign of destruction. One of the things that Ezekiel is doing here is he's enacting in visual form what had happened and what would happen
