And the king said unto Zadok, Carry back the ark of God into the city: if I shall find favour in the eyes of the LORD, he will bring me again, and shew me both it, and his habitation:

And the king said to Ziba, Behold, thine are all that pertained to Mephibosheth. And Ziba said, I humbly bow myself: may I find favour in thy sight, my lord, O king.
