2 Samuel 14:28-30

The Voice

²⁸ Absalom lived in Jerusalem for two years without seeing his father David, the king, ²⁹ and at last Absalom sent a message to Joab that he wanted to be brought before David. But Joab did not answer his summons. Absalom sent him a second message, and again Joab did not come. ³⁰ So Absalom gathered his servants and gave them orders.

The servants did as he ordered, and this got Joab’s attention.
