What does 2 Samuel 13:1 mean?
One of the Lord's consequences for David's sins of adultery and murder was that David's house would always be marked by the sword of violence (2 Samuel 12:10). This chapter describes the specific ways in which that judgment against David is fulfilled.It begins with the one-sided attraction of a man, Amnon, for a beautiful woman who happens to be his half-sister. He can't get her alone until his clever cousin devises a plan. Amnon will pretend to be even sicker than he already feels. He'll convince their father, King David, to send Tamar to give him food. If Amnon can then clear the room, he'll be able to do what he wants to Tamar (2 Samuel 13:3–5). Sadly, the plan works. This leads to humiliation, murder, and eventually a rebellion against David.
Amnon is David's oldest son. David married Amnon's mother, Ahinoam, the Jezreelite, before he became king of Judah (1 Samuel 25:43). Absalom is David's third son; his and Tamar's mother is Maacah, the daughter of the king of Geshur. Both sons were born in Hebron, after David became king of Judah. Tamar appears to be David's only daughter among David's wives' 19 sons (1 Chronicles 3:9).
