Ezekiel 9:4; Ezekiel 9:6

4 "Go through the whole city of Jerusalem and put a mark on the forehead of everyone who is distressed and troubled because of all the disgusting things being done in the city."

6 Kill the old men, young men, young women, mothers, and children. But don't touch anyone who has the mark on his forehead. Start here at my Temple." So they began with the leaders who were standing there at the Temple.
