Isaiah 10: 7-11. “Howbeit he meaneth not so, neither doth his heart think so: but it is in his heart to destroy and cut off nations not a few. For he saith, Are not my princes altogether kings? Is not Calno as Carchemish? is not Hamath as Arpad? is not Samaria as Damascus? As my hand hath found the kingdoms of the idols, and whose graven images did excel them of Jerusalem and of Samaria; Shall I not, as I have done unto Samaria and her idols, so do to Jerusalem and her idols?”
The Assyrian nation that God permitted to bring His judgment upon Ephraim and Judah is going to be in for its own judgment. They are proud, haughty, and just as godless and full of idolatry as Israel. They overstep themselves in their pride at all they have conquered. The king of Assyria was full of pride, intending to create a universal empire. So it has been throughout all of history, as nations rise and fall. A mere man, any man, is nothing more than a tool like an axe or a rod in God’s hand, used to bring judgment on whoever God wills, but then receiving judgment because of pride.
Calno, Carchemish, Hamath, Arpad. Why are these places significant? They were all cities that had fallen to the power of the Assyrian king and his army. He is saying here that no one can stand against him; not Samaria, and not Jerusalem with all their idols.
Not all of these events took place one after the other, but in a period of about 20 years. Assyria was a cruel taskmaster, going far beyond what God had ordained. They would pay dearly for their pride.
