Sephar in the Bible

Because the king of Assyria brought captives from Babylon, Cuthah, Avva, Hamath, and Sephar-vaim and settled them in the cities of Samaria to replace the Israelis, the settlers possessed Samaria and lived in its cities.

and settlers from Avva built Nibhaz and Tartak. The residents of Sephar-vaim burned their children in fire to Adrammelech and Anammelech, the gods of Sephar-vaim.

Where are the gods of Hamath and Arpad? Where are the gods of Sephar-vaim, of Hena, and Ivvah? Have they delivered Samaria from my control?

Where is the king of Hamath, the king of Arpad, the king of the city of Sephar-vaim, the king of Hena, or the king of Ivvah?'"
