John Trapp on Proverbs 10:18

Verſ. 18. Hee that hideth hatred, &c.] Theſe are dangerous creatures that thus lye at the catch, and wait advantages to do a man miſchief, as Cain dealt by Abel, Abſolom by Amnon, Joab by Amaſa, Judas by Jeſus, Tuta frequenſque via eſt, &c.

And hee that uttereth a ſlander, is a fool] Becauſe hee hath no command of his paſſions, as the former ſeems to have, becauſe cloſe in cloaking his malice, who yet is a fool too before God.
