Which person in the Bible murdered his half brother in revenge for raping his full sister?
“Absalom ordered his men, “Listen! When Amnon is in high spirits from drinking wine and I say to you, ‘Strike Amnon down,’ then kill him. Don’t be afraid. Haven’t I given you this order? Be strong and brave.” So Absalom’s men did to Amnon what Absalom had ordered. Then all the king’s sons got up, mounted their mules and fled. While they were on their way, the report came to David: “Absalom has struck down all the king’s sons; not one of them is left.””2 Samuel 13:28-30 (NIV)
