'Writer's' in the Bible

Behold, six men came from the way of the upper gate, which lies toward the north, every man with his slaughter weapon in his hand; and one man in the midst of them clothed in linen, with a writer's inkhorn by his side. They went in, and stood beside the bronze altar.

The glory of the God of Israel was gone up from the cherub, whereupon it was, to the threshold of the house: and he called to the man clothed in linen, who had the writer's inkhorn by his side.
