2 Samuel 15:21-22

And Ethai answered the king, saying: As the Lord liveth, and as my lord the king liveth: in what place soever thou shalt be, my lord, O king, either in death, or in life, there will thy servant be.

And David said to Ethai: Come, and pass over. And Ethai the Gethite passed, and all the men that were with him, and the rest of the people.
