'Living God' in the Bible

Then spake David to the men that stood by and said, "What shall be done to the man that beateth this Philistine and taketh away the shame from Israel? For what is this uncircumcised Philistine, that he should revile the host of the living God?"

For both a Lion and also a Bear hath thy servant slain. And this uncircumcised Philistine shall be as one of them, for his railing on the host of the living God."
