John Trapp on Psalms 33:3

Verſ. 3. Sing unto him a new Song] ſc. upon every new emergent occaſion. God reneweth his Mercies not only every morning, but every moment; ſo thould we out praiſes; every breath we draw ſhould praiſe the Lord, Pſal. 150. ult. Doth God give comforts? praiſe him, and they ſhall be continued. Doth hee ſend Croſſes? praiſe him, and they ſhall be removed, ſaith a Father; but in every thing [illegible: 1 word] thanks; and that not coldly and curſorily, but ardently, and with utmoſt affection; for which cauſe this duty is ſo reiterated here, and preſſed with ſuch forcible arguments in the following verſes, as might work upon the very ſtones almoſt; much more men, for whoſe ſakes all this fair Fabrick of the World was erected.

Play skilfully (or luſtily) with a loud noyfe] Make good Muſick, ſet all your skill and might a work to magnifie the Lord. It is not an eaſie matter to praiſe God aright; it muſt be done Corde, ore, oper[illegible: 1 letter], with the very beſt of the beſt. Benefacite canendo, cuns jubilatione.
