'Myself' in the Bible

And David sendeth messengers unto Ish-Bosheth son of Saul, saying, 'Give up my wife Michal, whom I betrothed to myself with a hundred foreskins of the Philistines.'

And the king saith to Ziba, 'Lo, thine are all that Mephibosheth hath;' and Ziba saith, 'I have bowed myself -- I find grace in thine eyes, my lord, O king.'

And I am perfect before Him, And I keep myself from mine iniquity.
