'Ink horn' in the Bible

And behold, six men came from the way of the upper gate, which is turned toward the north, and every man with his slaughter weapon in his hand; and in the midst of them, one man clothed with linen, with a writer's ink-horn by his side; and they went in, and stood beside the brazen altar.

And 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 with linen, who had the writer's ink-horn by his side;

And behold, the man clothed with linen, who had the ink-horn by his side, reported the matter, saying, I have done as thou hast commanded me.
