'Living God' in the Bible

David asked the men who were standing near him, "What will be done for the man who strikes down this Philistine and frees Israel from this humiliation? For who is this uncircumcised Philistine, that he defies the armies of the living God?"

Your servant has struck down both the lion and the bear. This uncircumcised Philistine will be just like one of them. For he has defied the armies of the living God!"
