Ezekiel 9:4-6

4And the LORD said to 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 are done in the midst of it.1

5And to the others he said in my 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 elders who were before the house.3
