Ezequiel 9

4 and said to him, Go through the midst of Jerusalem, and set a mark on the foreheads of the men that groan and that grieve for all the iniquities that are done in the midst of them. 5 And he said to the first in my hearing, Go after him into the city, and smite: and let not your eyes spare, and have no mercy. 6 Slay utterly old man and youth, and virgin, and infants, and women: but go ye not nigh any on whom is the mark: begin at my sanctuary.

So they began with the elder men who were within in the house.
