John Trapp on Proverbs 21:20

Verſ. 20. There is a treaſure to bee deſired] Hee had ſaid before, Hee that loveth Wine and Oyl ſhall not bee rich. Here hee ſhews, that though theſe things may not bee loved or laviſhed, yet they may, and muſt bee had and heaped up in a way of good husbrandry for neceſſity, yea for honeſt affluence; that wee may not onely live, but live comfortably; that wee may not onely have priſoners pittance, ſo much as will keep us alive, but that wee may have plenty of things deſirable, both for profit, as treaſure, and for delight, as oyl. And theſe things muſt not bee fooliſhly waſted (as they are uſually by unthrifts) leſt that make the wife that wants, angry and unquiet, as in the former verſe.
