Ezekiel 9:4-6

9:4 The Lord said to him, “Go through the city of Jerusalem and put a mark on the foreheads of the people who moan and groan over all the abominations practiced in it.”

9:5 While I listened, he said to the others, “Go through the city after him and strike people down; do no let your eye pity nor spare anyone! 9:6 Old men, young men, young women, little children, and women – wipe them out! But do not touch anyone who has the mark. Begin at my sanctuary!” So they began with the elders who were at the front of the temple.
