A Psalm for David
Sing to the Lord a new song, because the Lord has done marvelous things. His right hand has saved him, and His holy arm.
The Lord has made known his salvation before the Gentiles; He has revealed His righteousness. He has remembered His mercy to Jacob, and His truth to the house of Israel. All the ends of the earth have seen the salvation of our God.
Shout to God, all the earth, sing and rejoice and sing psalms. Sing psalms to the Lord on the harp, with harp and the voice of a psalm, with metal trumpets and a horn trumpet. Shout to the Lord before the king. Let the sea and its fulness be shaken, the inhabited world and those who inhabit it. Rivers will clap with hands in one accord; the mountains will rejoice. For He comes to judge the earth. He will judge the inhabited world in righteousness and peoples with straightness.
Now how do you think Paul would have read this psalm? Hays suggests we might have it in mind as we read:
"I am not ashamed of the gospel, for it is the power of God unto salvation to everyone who has faith--to the Jew first and also to the Greek. For in the gospel the righteousness of God is revealed from faithfulness leading to faith, as it is written, 'The person who is righteous on the basis of faith will live.' For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of humanity..." Hmmm.
