John Trapp on Psalms 17:5

Verſ. 5. Hold up my goings in thy paths, &c.] Keep me within the circle of thy Word, as thouhitherto haſt done; make me to walk exactly, and as in a frame, Epheſ. 5.15. Grant me thy preventing, concomitant, and ſubſequent grace; O thou God of all grace, perfect, ſtrengthen, ſtabliſh me, 1 Pet. 5.10.

That my foot-ſteps ſlip not] by the malice of Satan, who ſeeks to ſubvert ſuch as are moſt eminent, to the ſcandal of the weak, and ſcorn of the wicked; by the corruption alſo of mine own heart, Qua quiſ que ſibi Satan eſt, as one well faith, whereby every man is a Satan to himſelf; could we but divorce the fleſh from the Devil, there would be no ſuch danger: And laſtly, by the allurements, or affrightments of this preſent evil world; the way whereof is like the vale of Siddim, ſlimy, and ſlippery, full of Lime-pits, and Pit-falls, Springs, and ſtumbling-blocks.
