It’s because of David’s adultery and murder that his family was plagued with similar filth within.  His son, Amnon, did a horrible thing to David’s daughter, Tamar, in 2 Samuel 13 which caused another son to kill Amnon in vengeance.  This other son then did some pretty disgusting things himself while turning the nation against David.  In the end, this rebellious boy got his long hair stuck in a tree where he was killed.

What was the name of the tree hanger?
