I have always liked the story of Phinehas, Aaron’s grandson. For the uninitiated, Phinehas was a young priest who took it upon himself to execute the son of a Simeonite tribal chief in the act of committing adultery with a Midianite woman by impaling the two on the same spear. As a child, I found his rather decisive move a bit daring (not to mention violent), but also commendable and brave.
After all, a spontaneous impalement is both unilateral and very final. It tends to inspire the neighbors to murmur things like “I say, old boy, don’t you think that’s a bit drastic?” Or worse.
