19 Then said the king to Ittai the Gittite, Wherefore goest thou also with us? return, and abide with the king: for thou art a foreigner, and also an exile; [return] to thine own place. 20 Whereas thou camest but yesterday, should I this day make thee go up and down with us, seeing I go whither I may? return thou, and take back thy brethren; mercy and truth be with thee. 21 And Ittai answered the king, and said, As Jehovah liveth, and as my lord the king liveth, surely in what place my lord the king shall be, whether for death or for life, even there also will thy servant be. 22 And David said to Ittai, Go and pass over. And Ittai the Gittite passed over, and all his men, and all the little ones that were with him.

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.
