'Living God' in the Bible

Then spake David unto the men that were standing by him, saying, What shall be done to the man that shall smite yonder Philistine, and so shall take away reproach from off Israel? For who is this uncircumcised Philistine that he hath reproached the ranks of a Living God?

Thy servant could slay, either a lion or a bear, - and, this uncircumcised Philistine, shall become, as one of them, for he hath reproached the ranks of a Living God.
