'Scribe' in the Bible

Rehum the chancellor and Shimshai the scribe wrote a letter against Jerusalem to Artaxerxes the king in this sort:

Then wrote Rehum the chancellor, and Shimshai the scribe, and the rest of their companions; the Dinaites, the Apharsathchites, the Tarpelites, the Apharsites, the Archevites, the Babylonians, the Susanchites, the Dehavites, and the Elamites,

Then sent the king an answer unto Rehum the chancellor, and to Shimshai the scribe, and to the rest of their companions that dwell in Samaria, and unto the rest beyond the river, Peace, and at such a time.

Now when the copy of king Artaxerxes' letter was read before Rehum, and Shimshai the scribe, and their companions, they went up in haste to Jerusalem unto the Jews, and made them to cease by force and power.

This Ezra went up from Babylon; and he was a ready scribe in the law of Moses, which the LORD God of Israel had given: and the king granted him all his request, according to the hand of the LORD his God upon him.

Now this is the copy of the letter that the king Artaxerxes gave unto Ezra the priest, the scribe, even a scribe of the words of the commandments of the LORD, and of his statutes to Israel.

Artaxerxes, king of kings, unto Ezra the priest, a scribe of the law of the God of heaven, perfect peace, and at such a time.

And I, even I Artaxerxes the king, do make a decree to all the treasurers which are beyond the river, that whatsoever Ezra the priest, the scribe of the law of the God of heaven, shall require of you, it be done speedily,
