John Trapp on Psalms 68:28

Verſ. 28. Thy God hath commanded thy ſtrength] A brave expreſſion, admired by Longinus a Heathen Rhetorician. See the like Deut. 28.8. Pſal. 42.8. & 44.4. & 33.9. God both made and ruleth the World without Tool or toyl, he enableth his people to ſubſiſt, and to reſiſt their enemies by his Will only, and by the efficacy of his Word. Suppeditavit tibi Deus tantum robur, nequid ſuperbias, ſaith Varablus.

Strengthen, O God, that which thou haſt wrought for us] Petamus ut det, qued ut habeamus jubet. Pray to the God of all Grace, to make us the ſame that hee requireth us to be.
