13 Now a messenger came to David, saying, "The hearts of the men of Israel are with Absalom." 14 So David said to all his servants who were with him at Jerusalem, "Arise, and let us flee; or we shall not escape from Absalom. Make haste to depart, lest he overtake us suddenly and bring disaster upon us, and strike the city with the edge of the sword." 15 And the king's servants said to the king, "We are your servants, ready to do whatever my lord the king commands." 16 Then the king went out with all his household after him. But the king left ten women, concubines, to keep the house. 17 And the king went out with all the people after him, and stopped at the outskirts. 18 Then all his servants passed before him; and all the Cherethites, all the Pelethites, and all the Gittites, six hundred men who had followed him from Gath, passed before the king. 19 Then the king said to Ittai the Gittite, "Why are you also going with us? Return and remain with the king. For you are a foreigner and also an exile from your own place. 20 In fact, you came only yesterday. Should I make you wander up and down with us today, since I go I know not where? Return, and take your brethren back. Mercy and truth be 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.
