2 Samuel 19:9-10
9-10Meanwhile, the whole populace was now complaining to its leaders, "Wasn't it the king who saved us time and again from our enemies, and rescued us from the Philistines? And now he has had to flee the country on account of Absalom. And now this Absalom whom we made king is dead in battle. So what are you waiting for? Why don't you bring the king back?"
11-13When David heard what was being said, he sent word to Zadok and Abiathar, the priests, "Ask the elders of Judah, 'Why are you so laggard in bringing the king back home? You're my brothers! You're my own flesh and blood! So why are you the last ones to bring the king back home?' And tell Amasa, 'You, too, are my flesh and blood. As God is my witness, I'm making you the permanent commander of the army in place of Joab.'"
