John Trapp on Psalms 116:6

Verſ. 6 The Lord preſerveth the ſimple] Heb. The perſwaſible (oppoſed to the ſcorner, Prov. 19.25.) the plain-hearted (oppoſed to the guilefull, 2 Cor. 1.12. & 11.3. Rom. 16.19.) the deſtitute of humane help, that committeth himſelf to God, and patiently reſteth on him for ſupport and ſuccour, Pſal. 102.1 — 17.

I was brought low] Or, drawn dry; I was at a great under, at a low ebbe; I was exhauſted or emptied as a pond, ſtrengthleſſe, ſuccourleſſe, clean gone in a manner.

And hee helped mee] The knowledge that David had of Gods goodneſſe was experimentall. See the like, Rom. 8.2. A Carnal man knoweth Gods excellencies and will revealed in his word only, as wee know far Countries by Maps; but an experienced Chriſtian, as one that hath himſelf been long there, 1 Cor. 2.14, 15, 16.
