Ezekiel 9:4-6

4 and said to him, "Go through the city, through Jerusalem, and put a mark on the foreheads of those who sigh and groan over all the abominations that are committed in it."
5 To the others he said in my hearing, "Pass through the city after him, and kill; your eye shall not spare, and you shall show no pity.
6 Cut down old men, young men and young women, little children and women, but touch no one who has the mark. And begin at my sanctuary." So they began with the elders who were in front of the house.
