John Trapp on Psalms 103:18

Verſ. 18. To ſuch as keep his Covenant] For elſe they ſhall know Gods breach of promiſe, as it is Numb. 14.3, 4. Neither ſhall it benefit them to have been born of godly parents.

And to thoſe that remember his Commandements] That reſolve to do them, though in many things they fail, Qui faciunt praetepta etiamſ[illegible: 1 letter] non perficiant, that wiſh well to that which they can never compaſs, Pſal. 119.4, 5. If they cannot open the door, yet if they give a pluck at the bolt, or a lift at the latch, there is comfort.
