Instead of trusting in God's help (Isaiah 7:7–16), Ahaz asked Tiglath-pileser III of Assyria to save him from his enemies. Tiglath-pileser succeeded, leading to Rezin's death, the capture of Damascus, and the deportation of its people in 732 BC. This also helped remove Pekah as king of Israel that same year (2 Kings 15:29–30). However, the rescue was costly; Ahaz paid a large tribute, and Assyria's involvement made Judah a vassal state (a state under the control of another).
