2 Samuel 15:3-6, 10-12

Then Absalom would say, “Look, you’ve got a strong case; but the king isn’t going to listen to you.” Then he’d say, “Why doesn’t someone make me a judge for this country? Anybody with a case could bring it to me and I’d settle things fair and square.” Whenever someone would treat him with special honor, he’d shrug it off and treat him like an equal, making him feel important. Absalom did this to everyone who came to do business with the king and stole the hearts of everyone in Israel.

Then Absalom sent undercover agents to all the tribes of Israel with the message, “When you hear the blast of the ram’s horn trumpet, that’s your signal: Shout, ‘Absalom is king in Hebron!’” Two hundred men went with Absalom from Jerusalem. But they had been called together knowing nothing of the plot and made the trip innocently. While Absalom was offering sacrifices, he managed also to involve Ahithophel the Gilonite, David’s advisor, calling him away from his hometown of Giloh. The conspiracy grew powerful and Absalom’s supporters multiplied.
