John Trapp on Proverbs 26:21

Verſ. 21. So is a contentious man] Hebr. A man of contentions, Vir bilioſus & bellicoſus, a man made up of diſcords (as Democritus ſaid the world was) that loves to live in the fire, as the Salamander doth: the dog-dayes continue with ſuch all the year long, and like mad doggs, they bite and ſet a madding all they can faſten on, as did Sheba, Korah, and Judas, who ſet all the Diſciples a murmuring at the oyl poured on Chriſts head. So Arrius ſet all the Chriſtian world on a light fire, and Pope Hildebrand caſt abroad his firebrands.
