'Ink horn' in the Bible

And lo, six men are coming from the way of the upper gate, that is facing the north, and each his slaughter-weapon in his hand, and one man in their midst is clothed with linen, and a scribe's inkhorn at his loins, and they come in, and stand near the brazen altar.

And He calleth unto the man who is clothed with linen, who hath the scribe's inkhorn at his loins, and Jehovah saith unto him, 'Pass on into the midst of the city, into the midst of Jerusalem, and thou hast made a mark on the foreheads of the men who are sighing and who are groaning for all the abominations that are done in its midst.'

And lo, the man clothed with linen, at whose loins is the inkhorn, is bringing back word, saying, 'I have done as Thou hast commanded me.'
