Telassar

Telassar appears only in Sennacherib's taunting letter to Hezekiah (2 Kings 19:12, Isaiah 37:12), where the Assyrian king lists the cities his predecessors had crushed — Gozan, Haran, Rezeph, and "the children of Eden which were in Telassar" — as proof that no god could resist Assyria. The city was the capital of Bit-Adini (the "house of Eden" in the biblical text), an Aramean kingdom in the upper Euphrates bend. Shalmaneser III conquered it in 856 BCE. The biblical record turns the boast inside out: Sennacherib went home to be assassinated by his own sons, while Jerusalem stood untouched.
