What does Isaiah 10:25 mean?
Through Isaiah, the Lord is offering comfort to His suffering people in Judah (Isaiah 10:20–22). He is not, however, apologizing for their suffering. The Lord is the one who is causing it (Isaiah 10:23). He is using the Assyrians as an instrument of destruction against His people for their disobedience and faithlessness to Him. He wants them to understand that He has not, and will not, abandon them to that destruction.The Lord has told them not to fear the Assyrians because His fury against Israel will soon be satisfied (Isaiah 10:24). This judgment will be enough. His anger against them will end. Then He will turn His anger against the Assyrians. The Lord will punish the Assyrian's kings for their arrogance and boastfulness (Isaiah 10:12).
Even in judgment, the Lord wants His people to know that He is faithful and will keep His promises.
