But I will have mercy upon the house of Judah— This difference in the divine dispensation was owing to the enormous crimes of the Israelites, and to the singular piety of Hezekiah. Judah was saved in a miraculous manner from the sword of the Assyrians. It was not by bow, nor by sword, &c. but by the immediate and miraculous intervention of the Lord, who destroyed the Assyrian army in one night. See 2 Kings 19:35.
