Ezekiel 9:2-3

2Behold, six men [angelic beings] came from the direction of the Upper Gate, which faces north, each with his battle-axe in his hand; and among them was a certain man clothed in linen, with a scribe’s writing case at his side. They entered and stood beside the bronze altar.

3Then the [Shekinah] glory and brilliance of the God of Israel (the cloud) went up from the cherubim on which it had rested, to [stand above] the threshold of the [Lord’s] temple. And the Lord called to the man clothed with linen, who had the scribe’s writing case at his side.
