Sargon II was a king of Assyria. Isaiah says that King Sargon sent his supreme commander to Ashdod (a city in Israel), who attacked and captured it. Josiah, king of Judah, attacked the Egyptian army when Necho the king of Egypt went to help the king of Assyria; Josiah died in the battle.
Name and background
The name Sargon is an Aramaic rendition of the Accadian Šarru-ukīn derived from words meaning "king" or "prince" and "to establish". It was the name or title of the founder of an Abraham-era post-Babel empire based out of Accad. Apparently it was first use to authenticate the reign of the new king.
Years later, two kings in what became Assyria took the name. Sargon II came to power in a coup against his brother Shalmaneser who had defeated the forces of the northern kingdom of Israel in the ninth year of king Hoshea and the sixth year of Hezekiah, king of Judah. He seems to have worked along side his son and successor Sennacherib, putting his birth some 30 to 40 years before reign of Hezekiah, in the reign of king Jotham of Judah.
