Alright, so 1 Kings 1 starts off with an old King David getting old and weak, so his servants try to find a young buck to be the next king of Israel. They settle on one of his sons, Adonijah, and he starts throwing himself a big party to celebrate. But then it turns out that old King David actually wanted Solomon to be the next king, so Adonijah's party gets shut down before it even starts. Then King David makes Solomon king, and Adonijah and his buddies are like "Oh snap, that's not cool!" But then Solomon is like "Don't worry, I'll let you stay alive if you don't mess with me". So that's 1 Kings 1, everybody.
