John Trapp on Psalms 9:3

Verſ. 3. When mine enemies] This, Tremellius maketh to be the form of praiſe which the Pſalmiſt profeſſeth, that he will ſing to God, and rendereth it thus, That mine enemies returning back are fallen, &c.

And periſh at thy preſence] The victory is of God, and to him alone to be aſcribed. The Romans in their Triumphs preſented a Palm to Jupiter. The Graecians alſo thankfully aſcribed to Jupiter their deliverance from the Perſians, wrought by Themiſtocles, and there-hence called him [non-Latin text not transcribed], that is, Deliverer.
