John Trapp on Isaiah 38:17

Ver. 17. Behold for peace I had great bitterneſſe] Mar Mar; the approach of death was to this good man bitter bitterneſſe: and yet Chriſt had taken away from him the ſting (or gall) of death; ſo that he might better ſay then Agag did, Surely the bitterneſſe of death is paſt, or then Lucan doth of the Gaules and Britones, — animaeque capaces Mortis:

But thou haſt in love to my ſoul] Or, thou haſt embraced my ſoul out of the corrupting pit. Complectendi verbum, affectum planè paternum, & ſtudium juvandi ſingulare exprimit.

For thou haſt caſt all my ſins behind thy back] As an old oreworn evidence, that's out of date, and of no uſe. Here it is well noted, that we muſt ſet our ſins before our face, if we would have God to caſt them behind his back, Pſal. 50.2[illegible: 1 letter]. and 51.3.
