Ezekiel 9:5-6

5While I listened, the Lord said to the other men, ‘Follow that man through the city. Kill people who do not have his mark on their heads. Do not be sorry for them. Do not be kind to them.

6Kill the old men, young men and girls. Kill the women and the children. Destroy them all! But do not touch anyone who has the mark on their head.’ So the men started to kill. The first people that they killed were the city's leaders who were in front of the temple.
