'O Lord My God' in the Bible
And now, O LORD my God, thou hast made thy servant king instead of David my father: and I am but a little child: I know not how to go out or come in.
Yet have thou respect unto the prayer of thy servant, and to his supplication, O LORD my God, to hearken unto the cry and to the prayer, which thy servant prayeth before thee to day:
And he cried unto the LORD, and said, O LORD my God, hast thou also brought evil upon the widow with whom I sojourn, by slaying her son?
And he stretched himself upon the child three times, and cried unto the LORD, and said, O LORD my God, I pray thee, let this child's soul come into him again.
And David said unto God, Is it not I that commanded the people to be numbered? even I it is that have sinned and done evil indeed; but as for these sheep, what have they done? let thine hand, I pray thee, O LORD my God, be on me, and on my father's house; but not on thy people, that they should be plagued.
Have respect therefore to the prayer of thy servant, and to his supplication, O LORD my God, to hearken unto the cry and the prayer which thy servant prayeth before thee:
{Shiggaion of David, which he sang unto the LORD, concerning the words of Cush the Benjamite.} O LORD my God, in thee do I put my trust: save me from all them that persecute me, and deliver me:
O LORD my God, if I have done this; if there be iniquity in my hands;
Consider and hear me, O LORD my God: lighten mine eyes, lest I sleep the sleep of death;
O LORD my God, I cried unto thee, and thou hast healed me.
To the end that my glory may sing praise to thee, and not be silent. O LORD my God, I will give thanks unto thee for ever.
Judge me, O LORD my God, according to thy righteousness; and let them not rejoice over me.
For in thee, O LORD, do I hope: thou wilt hear, O Lord my God.
Many, O LORD my God, are thy wonderful works which thou hast done, and thy thoughts which are to us-ward: they cannot be reckoned up in order unto thee: if I would declare and speak of them, they are more than can be numbered.
I will praise thee, O Lord my God, with all my heart: and I will glorify thy name for evermore.
Bless the LORD, O my soul. O LORD my God, thou art very great; thou art clothed with honour and majesty.
Help me, O LORD my God: O save me according to thy mercy:
I went down to the bottoms of the mountains; the earth with her bars was about me for ever: yet hast thou brought up my life from corruption, O LORD my God.
Art thou not from everlasting, O LORD my God, mine Holy One? we shall not die. O LORD, thou hast ordained them for judgment; and, O mighty God, thou hast established them for correction.
