John Trapp on Psalms 103:1

PSAL. CIII.

A Pſalm of David] Which he wrote when carried out of himſelf, as far as heaven, ſaith Beza; and therefore calleth not upon his own ſoul onely, but upon all creatures from the higheſt Angel, to the loweſt worm, to ſet forth Gods praiſes.

Verſ. 1. Bleſs the Lord, O my ſoul] Agedum animul[illegible: 1 letter] mi, & intima mea viſera. A good mans work lyeth moſt within doors; he is more taken up with his own heart, than with all the world beſides; neither can he ever be along ſo long as he hath God and his own ſoul to converſe with. Davids Harp was not of[illegible: 1 letter]ner out of tune, than his heart, which here he is ſetting right, that he may the better make melody to the Lord. Muſick is ſweet, but the ſetting of the ſtrings in tune is unpleaſing; ſo is it harſh to ſet out hearts in order, which yet muſt be done, and throughly done, as here.

And all that is within me] All my faculties and ſenſes. The whole ſoul and body muſt be ſet a work in this ſervice; the judgement to ſet a right eſtimate upon mercies; the memory to recognize and retain them, Dent. 6 11, 12. and 8.14. the Will which is the proper ſeat of thankfulneſs; the affections, love, deſire, joy, confidence, all muſt bee actuated, that our praiſes may be cordial, vocal, vital. In peace-offerings God called for the ſat and inwards.
