David and his mob, they went to the top of the hill called Olive Trees Hill. People used to show respect to God at that place. A man called Hushai was there to join up with David’s mob. He was from the Arek mob, and he worked for David. You see, he heard about Absalom’s plan to attack Jerusalem, and he was sad for his boss. He even tore his clothes and put dirt on his head, to show he was sad.
