'Living God' in the Bible

David spoke to the men who were standing with him: “What will be done for the man who kills that Philistine and removes this disgrace from Israel? Just who is this uncircumcised Philistine that he should defy the armies of the living God?”

Your servant has killed lions and bears; this uncircumcised Philistine will be like one of them, for he has defied the armies of the living God.”
