In that day the remnant of Israel, the survivors of Jacob, will no longer rely on him who struck them down but will truly rely on the LORD, the Holy One of Israel. A remnant will return, a remnant of Jacob will return to the Mighty God. Though your people be like the sand by the sea, Israel, only a remnant will return. Destruction has been decreed, overwhelming and righteous. The Lord, the LORD Almighty, will carry out the destruction decreed upon the whole land. Isaiah 10:20-23
Judah’s reliance on Assyria for deliverance from the attack of Israel and Syria (Aram) results is God’s judgment on Judah for not trusting in Him to save them from Israel and Syria. God will then use Assyria as that judgment. The Lord promises Judah they are going through the judgment because they did not trust in the Lord, but He will change them so they will once again depend on the Lord. There will be a remnant that trusts in the Lord, and the Lord will direct His wrath to destroy the Assyrians. As the scriptures repeated say, the Lord is slow to anger, abounding in love and forgiving sin and rebellion. The Lord wants you, and all, to be saved. Turn your hearts to Him, it is never too late to repent and receive forgiveness from God.
