Ezekiel 9:5; Ezekiel 9:6

5 But to the others He said in my hearing, "Go through the city after him and strike; do not let your eye have pity and do not spare.

6 "Utterly slay old men, young men, maidens, little children, and women, but do not touch any man on whom is the mark; and you shall start from My sanctuary." So they started with the elders who were before the temple.
