Ezekiel 9:1-2

Then He cried out in my hearing with a loud voice saying, “Draw near, O executioners of the city, each with his destroying weapon in his hand.” Behold, six men came from the direction of the upper gate which faces north, each with his shattering weapon in his hand; and among them was a certain man clothed in linen with a writing case at his loins. And they went in and stood beside the bronze altar.
