13 Someone came to David with the report, "The whole country has taken up with Absalom!" 14 "Up and out of here!" called David to all his servants who were with him in Jerusalem. "We've got to run for our lives or none of us will escape Absalom! Hurry, he's about to pull the city down around our ears and slaughter us all!" 15 The king's servants said, "Whatever our master, the king, says, we'll do; we're with you all the way!" 16 So the king and his entire household escaped on foot. The king left ten concubines behind to tend to the palace. 17 And so they left, step by step by step, and then paused at the last house 18 as the whole army passed by him - all the Kerethites, all the Pelethites, and the six hundred Gittites who had marched with him from Gath, went past. 19 The king called out to Ittai the Gittite, "What are you doing here? Go back with King Absalom. You're a stranger here and freshly uprooted from your own country. 20 You arrived only yesterday, and am I going to let you take your chances with us as I live on the road like a gypsy? Go back, and take your family with you. And God's grace and truth go with you!"

Commentary on 2 Samuel 15:13-23
(Read 2 Samuel 15:13-23)
David determined to quit Jerusalem. He took this resolve, as a penitent submitting to the rod. Before unrighteous Absalom he could justify himself, and stand out; but before the righteous God he must condemn himself, and yield to his judgments. Thus he accepts the punishment of his sin. And good men, when they themselves suffer, are anxious that others should not be led to suffer with them. He compelled none; those whose hearts were with Absalom, to Absalom let them go, and so shall their doom be. Thus Christ enlists none but willing followers. David cannot bear to think that Ittai, a stranger and an exile, a proselyte and a new convert, who ought to be encouraged and made easy, should meet with hard usage. But such value has Ittai for David's wisdom and goodness, that he will not leave him. He is a friend indeed, who loves at all times, and will adhere to us in adversity. Let us cleave to the Son of David, with full purpose of heart, and neither life nor death shall separate us from his love.
