'Living God' in the Bible

David asked the men who were standing by him, "What will be done for the man who kills this Philistine and takes away the reproach from Israel? Indeed, who is this uncircumcised Philistine that he should defy the armies of the living God?"

Your servant has struck down both lions and bears, and this uncircumcised Philistine will be like one of them, since he defied the armies of the living God."
