(exalted?) king of Ethiopia (Cush), the opponent of Sennacherib (2 Kings 19:9; Isaiah 37:9). He may be identified with Tarkos or Tarakos, who was the third and last king of the twenty-fifth dynasty, which was of Ethiopians. His accession was probably about B.C. 695. Possibly Tirhakah ruled over Ethiopia before becoming king of Egypt.
