'Ink' in the Bible

Then Baruch answered them, “He dictated all these words to me, and I wrote them with ink on the scroll.”

Behold, 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.

Then 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.

But to the others I heard Him say, “Follow him [the man with the scribe’s writing case] throughout the city and strike; do not let your eyes have pity and do not spare [anyone].

Then behold, the man clothed in linen, who had the scribe’s writing case at his side, reported, “I have done just as You have commanded me.”
