Scoundrels and Saints, II Samuel 3-4, OT S1:E174

Abner, offended by Ishbosheth, swears an oath to bring Israel under David's rule. This leader of a military coup makes covenant with David, who welcomes him gladly. Sadly, or gladly, both Abner and Ishbosheth meet a bloody end, as scoundrels end their lives. Here we see God use human treachery to solidify David's reign.
