Ezekiel 9:4, 6

He said to the man, “Go through Jerusalem and put a mark on the foreheads of the people who groan and cry about all the hateful things being done among them.”

Kill and destroy old men, young men and women, little children, and older women, but don’t touch any who have the mark on them. Start at my Temple.” So they started with the elders who were in front of the Temple.
