John Trapp on Psalms 32:4

Verſ. 4. For day and night thy hand was heavy upon mee] See what God can do when once he taketh a man to do. Day and night hee had ſinned againſt God; therefore day and night he ſuffereth; and glad he may be that he ſo ſcapeth, and is not forced to undergo an eternity of extremity. Some think that this Pſalm, and the ſixth, were made much about a time; when David was newly recovered of ſome grievous fit of ſickneſſe. It may be meant only of his inward terrours, or chiefly at leaſt; his body ſuffering by Sympathy, as having ſhared in his ſin.

My moiſture is turned into the drought of Summer] My naturall radicall moiſture, that oyl that maintaineth the lamp of life, is dryed up and become like a lump of clay; the vigour alſo and verdure of my ſoul is quelled and conſumed with the fire of thy fierce wrath. God will bring his beſt people to this, if they put him to it; that they ſhall find it to be the greateſt folly in the World, to buy the ſweeteſt ſin at ſo dear a rate.

Selah] I ſpeak it feelingly.Vat. O quantum tormentum, &c. O aridum & exhauſtuns me prae maſtitia, &c. O my pittifull condition!
