2 Samuel 9:6

Mephibosheth, the son of Jonathan, the son of Saul, came to David, fell on his face, and showed respect. David said, “Mephibosheth?” He answered, “Behold, your servant!”

Now when Mephibosheth, the son of Jonathan, the son of Saul, was come unto David, he fell on his face, and did reverence. And David said, Mephibosheth. And he answered, Behold thy servant!
