New Defender's Study Bible Notes
51:11 thy holy spirit. Since the death and resurrection of Christ, He has promised that the Holy Spirit will indwell His believing disciples forever (John 14:16-17). Before Christ, the Holy Spirit would come upon individuals for specific empowerment for service and could as easily leave, as in the case of Saul (I Samuel 11:6; 16:14). David earnestly prayed that this would not happen also to him.
