Ezekiel 9:2-6

2And I saw six men coming from the direction of the Upper Gate, which faces north, each with a weapon of slaughter in his hand. With them was another man clothed in linen who had a writing kit at his side. And they came in and stood beside the bronze altar.

3Then the glory of the God of Israel rose from above the cherubim, where it had been, and moved to the threshold of the temple. And He called to the man clothed in linen who had the writing kit at his side. 4“Go throughout the city of Jerusalem,” said the LORD, “and put a mark on the foreheads of the men sighing and groaning over all the abominations committed there.”

5And as I listened, He said to the others, “Follow him through the city and start killing; do not show pity or spare anyone! 6Slaughter the old men, the young men and maidens, the women and children; but do not go near anyone who has the mark. Now begin at My sanctuary.”

So they began with the elders who were before the temple.
