In view of all the wonders God had done for him, it was unpardonable that Hezekiah did not feel himself prompted at least to sing a song of praise to God. Indeed, when the prophet Isaiah urged him to it, he refused, saying that the study of the Torah, to which he devoted himself with assiduous zeal, was a substitute for direct expressions of gratitude. Besides, he thought God's miracles would become known to the world without action on his part, in such ways as these: After the destruction of the Assyrian army, when the Jews searched the abandoned camps, they found Pharaoh the king of Egypt and the Ethiopian king Tirhakah.
These kings had hastened to the aid of Hezekiah, and the Assyrians had taken them captive and clapped them in irons, in which they were languishing when the Jews came upon them. Liberated by Hezekiah, the two rulers returned to their respective realms, spreading the report of the greatness of God everywhere. And again, all the vassal troops in Sennacherib's army, set free by Hezekiah, accepted the Jewish faith, and on their way home they proclaimed the kingdom of God in Egypt and in many other lands.
