2 Samuel 13 — What was wrong with Jonadab that he was offering advice to Amnon on how to break the law (v. 5)? And what was wrong with Amnon that he so strongly desired to sleep with his sister? They both had to know that it was forbidden for brothers and sisters to have sex (Lev. 18:9, 11; 20:17). It’s interesting how the beginning of the narrative describes Amnon’s feelings as “love” (v. 1) when we find out that he really hated her with a very great hatred (v. 15). This incident helps to put Deuteronomy 22:28-29 into focus. Tamar was just violated and she knows that the only thing worse than having been raped is Amnon not taking her as his wife (v. 16). I understand completely what Absalom did and why he did it. It’s what I’d want to do. When I read the account I’m rotting for Absalom here. It’s a shame that he fled.
2 Samuel 14 — If David was “comforted about Amnon” (2 Sam. 13:39), and his heart went out to Absalom (v. 1), then why did he need to be duped into allowing him to return (vv. 2-20), and why did he refuse to have him in his presence once he did return (v. 24)? And with all this talk about how handsome Absalom was (vv. 25-26) I start thinking about Saul, although David was handsome too, so it could go either way.
2 Samuel 15 — Yup, Absalom is like Saul, wicked, conniving, and scheming. This is the first time that we read about the Mount of Olives (v. 30) in Scripture. The only other time in the OT is in Zechariah 14:4, which is a messianic prophecy. David, of course, is a type of the Messiah, although here he ascends the mountain weeping with his head covered. In Zechariah’s prophecy the LORD descends and plants his feet on the Mount of Olives splitting it in two. These are decidedly different postures. Jesus’ Olivet Discourse (Matt. 24; Mark 13; Luke 21) is an elaboration on Zechariah 14.
