There is no reason to believe, from the biblical account, that Sennacherib was slain by his sons _immediately_ after his return to Nineveh; on the contrary, the expression "he returned and dwelt at Nineveh," infers that he continued to reign for some time over Assyria. We have accordingly his further annals on the monuments he erected. In his fourth year he went southward, and subdued the country of Beth-Yakin, defeating Susubira, the Chaldæan, who dwelt in the city of Bittut on the river--(Agammi, according to Rawlinson). Further mention is made of Merodach Baladan. "This king whom I had defeated in a former campaign, escaped from my principal servants and fled to an island (name lost); his brothers, the seed of his father's house, whom he left behind him on the coast, with the rest of the men of his country from Beth-Yakin, near the _salt_ (?) river (the Shat-el-Arab, or united waters of the Tigris and Euphrates), I carried away, and several of his towns I threw down and burnt; Assurnad_immi_ (? Assurnadin, according to Rawlinson), my son, I placed on the throne of his kingdom." He appears then to have made a large government, of which Babylon was the chief place. In the fifth year he defeated the Tokkari, capturing their principal stronghold or Nipour (_detached hill-fort_ ?), and others of their castles. He also attacked Maniyakh, king of _Okku_ or _Wukku_ (?), a country to which no previous Assyrian king had penetrated. This chief deserted his capital and fled to a distance. Sennacherib carried off the spoil of his palace and plundered his cities. This expedition seems to have been to the north of Assyria in Armenia or Asia Minor.
