Orth.—Listen now how the prophet praises God at the very beginning of the Psalm. He saw with his prophetic eyes the future iniquity of his people, and the captivity that was in consequence foredoomed; yet he praised his own Lord for unfailing promises. “I will sing,” he says, “of the mercies of the Lord forever, with my mouth will I make known Thy faithfulness to all generations, for thou hast said, Mercy shall be built up for ever, Thy faithfulness shalt Thou establish in the very heavens.”
