During the invasion, the Philistines and Edomites were taking advantage of the situation and raiding towns and villages within the Southern Kingdom. Ahaz called out to Tiglath-Pileser III of Assyria for help. The Assyrians defended Judah, conquering Israel, Syria, and the Philistines, but the post-war alliance only brought more trouble for the king of Judah. Ahaz had to pay tribute to Tiglath-Pileser III with treasures from the Temple in Jerusalem and the royal treasury. He also built idols of Assyrian gods in Judah to find favor with his new ally.
