The altar — Of burnt — offering before the temple at Jerusalem, this altar and temple Israel had forsaken, and set up others against it; and here God in his jealousy appears prepared to take vengeance. Possibly it may intimate his future departure from Judah too. There Ezekiel, Ezekiel 9:2, saw the slaughter — men stand. The door — The door of the gate that led into the priests court. And cut them — Wound deep, the people who were visionally represented as standing in the court of the temple.

1 I saw the Lord standing upon the altar: and he said, Smite the lintel of the door, that the posts may shake: and cut them in the head, all of them; and I will slay the last of them with the sword: he that fleeth of them shall not flee away, and he that escapeth of them shall not be delivered.
