Psalms 17:5

Hold up my goings in thy paths, [that] my footsteps slip not.

Ver. 5. Hold up my goings in thy paths, &c.] Keep me within the circle of thy word, as thou hitherto hast done; make me to walk exactly, and as in a frame, Ephesians 5:15. Grant me thy preventing, concomitant, and subsequent grace: O thou God of all grace, perfect, strengthen, stablish me, 1 Peter 5:10 .

That my footsteps 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 quisque sibi Satan est, as one well saith, 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 slime pits and pit falls, springs and stumblingblocks.
