1. Absalom kills Amnon (23-29)

Absalom, the brother of Tamar, never said a word to Amnon, either good or bad (21). Rather, Absalom prepared for his sister's revenge. Two years later, Absalom urged David and all his sons to join him for a feast. David refused, but blessed his son. Then Absalom requested Amnon to attend. David sensed that this would not be a good idea, but when Absalom continued to urge him, he gave into his son's request and sent all his sons including Amnon, to Absalom to attend the banquet. When Amnon was drunk, Absalom ordered his servants to kill him. Thus, Amnon paid with his life for the wages of his sin of rape.

2. The tragic consequences of sin (30-39)

After David's adultery and homicide, his newborn baby died (12:18). Amnon raped Tamar. Absalom, brother of Tamar killed Amnon. And now Absalom fled. David had lost three sons and suffered more and more as the consequences of his sin were getting worse. The tragedy of sin was not finished (12:13, ch.15-17).
