Isaiah 10:12. “Wherefore it shall come to pass, that when the Lord hath performed His whole work upon mount Zion and on Jerusalem, I will punish the fruit of the stout heart of the king of Assyria, and the glory of his high looks.”
The king of Assyria, the nation of Assyria, did not have a heart for God. They wanted to conquer every nation, not for God’s glory but for their own. God used them, and allowed them to be His instrument of justice on an hypocritical, idolatrous Israel; they, however, had no knowledge of Jehovah, God of Israel. They just did what they always had done. They warred on surrounding nations and swallowed them up. Assyria was famous for its really incredible cruelty, not for its holiness, justice or mercy.
The king had an arrogant heart and a haughty appearance. He would pay dearly.
It’s too bad that there are similar men, similar nations today who have no heart for God. They are arrogant and haughty, thinking they have all the power. They, too, will pay dearly. God is not mocked. Whatever a man sows, that’s what he will reap (Galatians 6:7).
