The answer is: Joab

2 Sam 3:29

In the vivid tapestry of the biblical narrative, Joab's infamous deception and violent actions certainly give rise to deep consequences. Joab, the commander of King David's army, engaged in some pretty morally murky deeds, one of which was the assassination of Abner, a once-enemy turned ally. 2 Samuel 3:29 captures God’s curse as one that wasn’t very specific but very public—invoking the severed fates from his deeds, possibly in terms of generational consequences, paralleling the idea that misdeeds reflect back on the transgressor's lineage.

The association between Joab's actions and their spiritual fallout is robust, echoing the larger theme of justice throughout the Scriptures. You see, in ancient Israel, leprosy wasn't just a physical ailment; it represented isolation and being cut off from the community, much like Joab distanced himself from genuine leadership through bloodshed.

Interestingly, leprosy, looking at it structurally, acted as a powerful metaphor - just like Joab's warrior ethos it inherently kept the bearer at odds with societal norms of purity and public morality. And if we go on a trivia trip through the Bible, did you know that Moses' sister Miriam faced a similar fate when she spoke against him, causing her to be leprous for a time? Both examples reinforce the moral imperative that embedded within the biblical text is the belief that the highest virtues should compel leaders to acts of justice and goodwill, rather than treachery.
