Ezekiel 9:4-6

4And Yhwh said unto him, Go through the midst of the city, through the midst of Jerusalem, and set a mark upon the foreheads of the men that sigh and that cry for all the abominations that be done in the midst thereof.1

5And to the others he said in mine hearing, Go ye after him through the city, and smite: let not your eye spare, neither have ye pity:2 6Slay utterly old and young, both maids, and little children, and women: but come not near any man upon whom is the mark; and begin at my sanctuary. Then they began at the ancient men which were before the house.3
