Biblical accounts.
The Hebrew Bible mentions it for one of Sennacherib's messengers to Hezekiah, who was sent to Jerusalem along with the Tartan and the Rabsaris. The speech he delivered, in the Hebrew language, in the hearing of all the people, as he stood near the wall on the north side of the city, is quoted in 2 Kings and in Isaiah .
