This verse continues to keep our focus on the works of the Lord. With one blow, God ended the war. Sennacherib’s army was destroyed, and he was humiliated before Jerusalem. It is supposed that Hezekiah destroyed the spoils of war instead of taking them for himself. Chariots had little military value, especially in the mountainous area of Judah, and the Lord restricted their use in Israel (Deuteronomy 17:16). God’s people had to live by faith in him and not by faith in horses and chariots: Some trust in chariots and some in horses, but we trust in the name of the Lord our God
(Psalm 20:7).
9 He makes wars cease to the end of the earth; he breaks the bow and shatters the spear; he burns the chariots with fire.
