2 Samuel 15:21-22

And Ittai answereth the king and saith, `Jehovah liveth, and my lord the king liveth, surely in the place where my lord the king is--if for death, if for life, surely there is thy servant.'

And David saith unto Ittai, `Go and pass over;' and Ittai the Gittite passeth over, and all his men, and all the infants who are with him.
