“Then Trypho said, "We know that you quoted these because we asked you. But it does not appear to me that this Psalm which you quoted last from the words of David refers to any other than the Father and Maker of the heavens and earth. You, however, asserted that it referred to Him who suffered, whom you also are eagerly endeavouring to prove to be Christ." And I answered, "Attend to me, I beseech you, while I speak of the statement which the Holy Spirit gave utterance to in this Psalm; and you shall know that I speak not sinfully, and that we are not really bewitched; for so you shall be enabled of yourselves to understand many other statements made by the Holy Spirit. 'Sing unto the Lord a new song; sing unto the Lord, all the earth: sing unto the Lord, and bless His name; show forth His salvation from day to day, His wonderful works among all people.' He bids the inhabitants of all the earth, who have known the mystery of this salvation, i.e., the suffering of Christ, by which He saved them, sing and give praises to God the Father of all things, and recognise that He is to be praised and feared, and that He is the Maker of heaven and earth, who effected this salvation in behalf of the human race, who also was crucified and was dead, and who was deemed worthy by Him (God) to reign over all the earth. As [is clearly seen] also by the land into which [He said] He would bring [your fathers]; [for He thus speaks]: 'This people [shall go a whoring after other gods], and shall forsake Me, and shall break my covenant which I made with them in that day; and I will forsake them, and will turn away My face from them; and they shall be devoured, and many evils and afflictions shall find them out; and they shall say in that day, Because the Lord my God is not amongst us, these misfortunes have found us out. And I shall certainly turn away My face from them in that day, on account of all the evils which they have committed, in that they have turned to other gods.'”

“In Psalm 95 [LXX] the coming of the Lord to humankind is again foretold, and that a new song, by which is meant the new covenant, will be sung by the whole earth at his coming, not by the Jewish race; and that the good news will no longer be for Israel but for all the nations, since it says that the Lord who is to come will be their King. Who could this be but God the Word, who, intending to judge the world in righteousness and the human race in truth, considers all people in the world equally worthy of his call, and consequently of the salvation of God?”

“We have said what house it is; now we must say after what captivity. The psalm shows you this too. Carry on a little: "Sing to the Lord a new song, sing to the Lord, all the earth. Sing to the Lord, bless his name, proclaim from day to day the gospel of his salvation. Proclaim among the nations his wonders, in all peoples his glory. Since all the gods of the nations are demons." There you are again, that is under whom the house was held in captivity. From the first transgression of the first human being, the whole human race, being born in the shackles of sin, was the property of the devil who had conquered it. After all, if we had not been held in captivity, we would not have needed a redeemer.”

“Declare his glory among the Heathen,.... What a glorious Person the Messiah is; the brightness of his Father's glory; having all the perfections of deity in him; how the glory of God appears in him, and in all that he has done; and especially in the work of redemption, in which the glory of divine wisdom, power, justice, truth, and faithfulness, love, grace, and mercy, is richly displayed; say what glory he is advanced unto, having done his work, being highly exalted, set at the right hand of God, and crowned with glory and honour; and what a fulness of grace there is in him, for the supply of his people; and what a glory is on him, which they shall behold to all eternity: his wonders among all people: what a wonderful person he is, God manifest in the flesh; what wonderful love he has shown in his incarnation, obedience, sufferings, and death; what amazing miracles he wrought, and what a wonderful work he performed; the work of our redemption, the wonder of men and angels; declare his wonderful resurrection from the dead, his ascension to heaven, sitting at the right hand of God, and intercession for his people; the wonderful effusion of his Spirit, and the conquests of his grace, and the enlargement of his kingdom in the world; as also what wonders will be wrought by him when he appears a second time; how the dead will be raised and all will be judged.”
