9 Meanwhile, 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. 10 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 When 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? 12 You're my brothers! You're my own flesh and blood! So why are you the last ones to bring the king back home?' 13 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.'" 14 He captured the hearts of everyone in Judah. They were unanimous in sending for the king: "Come back, you and all your servants." 15 So the king returned. He arrived at the Jordan just as Judah reached Gilgal on their way to welcome the king and escort him across the Jordan.

God's providence, by the priests' persuasions and Amasa's interest, brought the people to resolve the recall of the king. David stirred not till he received this invitation. Our Lord Jesus will rule in those that invite him to the throne in their hearts, and not till he is invited. He first bows the heart, and makes it willing in the day of his power, then rules in the midst of his enemies, Psalm 110:2,3.
