'O God' in the Bible

For this thou wert great, Jehovah God: for none as thee, for no God beside thee according to all we heard in our ears.

And it will be David came even to the head where he will worship there to God, and behold, to his meeting, Hushai the Archite, his tunic rent and earth upon his head.

In straits to me I will call Jehovah, And to God will I call, And he will hear my voice from his temple, And my cry in his ears.

For who God besides Jehovah? And who a rock besides our God?
