2 Kings 24:3,4 - Joseph Benson’s Commentary on the Old and New Testaments

To remove them out of his sight for the sins of Manasseh Properly and directly for their own sins, and remotely for the sins of Manasseh; who had so corrupted the whole body of the people, that they were become incurable, and Josiah's reformation had no lasting influence to recover them: for, immediately upon his death, they relapsed into their old idolatry, and other vices. Manasseh's personal sins, although, as he was their chief ruler, they were to be considered as national sins, and merited national punishment, yet would never have been charged on the nation, unless they had made them their own by their impenitency for them, and repetition of them. And for the innocent blood which he shed Namely, of those prophets and saints, who either reproved, or would not comply with his idolatrous worship. Which the Lord would not pardon That is, would not remit the temporal punishment of the land, though he did pardon it so as not to inflict eternal punishment upon his own person, for from that God undoubtedly exempted him upon his repentance. God is the righteous governor of the world, and the guardian of civil society, and in it order could not be preserved, if he did not interpose in his providence, and, on proper occasions, cause signal and national judgments to follow public and national crimes.
