Psalm 98:2
1 A psalm. Sing to the Lord a new song, for he performs amazing deeds. His right hand and his mighty arm accomplish deliverance. 2 The Lord demonstrates his power to deliver; in the sight of the nations he reveals his justice. 3 He remains loyal and faithful to the family of Israel. All the ends of the earth see our God deliver us. 4 Shout out praises to the Lord, all the earth. Break out in a joyful shout and sing! 5 Sing to the Lord accompanied by a harp, accompanied by a harp and the sound of music. 6 With trumpets and the blaring of the ram’s horn, shout out praises before the king, the Lord.
Romans 1:16
13 I do not want you to be unaware, brothers and sisters, that I often intended to come to you (and was prevented until now), so that I may have some fruit even among you, just as I already have among the rest of the Gentiles. 14 I am a debtor both to the Greeks and to the barbarians, both to the wise and to the foolish. 15 Thus I am eager also to preach the gospel to you who are in Rome. 16 For I am not ashamed of the gospel, for it is God’s power for salvation to everyone who believes, to the Jew first and also to the Greek. 17 For the righteousness of God is revealed in the gospel from faith to faith, just as it is written, “The righteous by faith will live.”
Notes and References
"... The keynote of Paul's exposition sounds in Rom. 1:16-17: "I am not ashamed of the gospel, for it is the power of God for salvation [soterian] to everyone who believes, to the Jew first and also to the Greek. For through the gospel the righteousness of God [dikaiosyne theou] is revealed [apokalyptetai], from faith for faith, just as it is written, 'The righteous one shall live from faith.'" All the crucial theological terms of this programmatic declaration echo the language of the LXX; indeed, in certain LXX passages these terms converge in ways that prefigure Paul's formulation strikingly. Consider, for example, Ps. 97:2 (98:2MT): "The Lord has made known his salvation [soterion]; in the presence of the nations [ethnon] he has revealed [apekalypsen] his righteousness [dikaiosynen]." This psalm verse tolls a Vorklang of Paul's proclamation-a tone whose echo rebounds with greater force than the original sound. Paul means, of course, that God's righteousness is revealed through the death and resurrection of Jesus Christ, but his evocation of the psalmist's language hints at a conviction that he articulates explicitly elsewhere: God's grace in Jesus Christ simultaneously extends salvation to the Gentiles and confirms Israel's trust in God's saving righteousness (see Rom. 15:8-9a) ..."
