His Name is Great in Israel
This psalm is a song of praise to God for saving the Nation of Israel from its enemies. Though it is unclear to which specific battle this psalm refers, contemporary author Amos Hakham points to the Septuagint, which adds the words “regarding the Assyrian” into the title of the psalm. This certainly refers to the battle recorded in Kings II (18-19), which took place in the eighth century BCE between Sennacherib, king of Assyria, and the kingdom of Judah under the leadership of King Hezekiah.
Assyria had conquered Mesopotamia and the ten tribes of Israel, dispersing them throughout his empire. Their emissaries stood at the gates of Jerusalem and warned Hezekiah of impending doom. The prophet Isaiah assured the king that God would bring salvation to Judah and protect them from harm. Miraculously, Sennacherib’s army mysteriously died overnight and the Assyrians returned home without conquering Jerusalem. This might explain the statement “God has made Himself known in Judah,” since as a result of this incident, all kingdoms heard that God battles on behalf of Judah and Jerusalem God is known to be in Judah.
