'Chancellor' 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.
