Theodoret of Cyrus : It was not a need for money that caused me to deliver you to the Babylonians but the will to make you atone for your iniquity; nevertheless, I am going to make you a gift of freedom again. For Isaiah has called the bondage a "furnace of poverty." In a furnace the fire itself remains hidden, and only the smoke released from the furnace can be seen. Likewise, prisoners of war do not dare to lament openly, but in their hearts. For they are consumed by the flame of discouragement, and their groan rises like a kind of smoke.… Since the enemies thought they had triumphed, not only over you but even over me, and that it was my weakness that had allowed them to dominate you, I will liberate you from this bitter slavery to the extent that even those who do not know me will hear of my might. — COMMENTARY ON Isaiah 15:48.10-11
