You might say the official method for healing is "the foundation of . . . the laying on of hands" (Heb 6:1). People were aware of this because "they begged him to place his hand on the man" (Mk 7:32). Jairus "pleaded earnestly with him . . . come and put your hands on her so that she will be healed and live" (Mk 5:23). Laying on of hands is doctrine because it was part of the Old Covenant and used in the annual festivals. The priests were to "lay their hands on its head" (Ex 29:10). This transferred the sins of the people to the sacrifice which was a type of Christ.
"Jesus put his hands on the [blind] man's eyes. Then his eyes were opened, his sight was restored" (Mk 8:25). In the synagogue where he was teaching Jesus saw a crippled woman. He said to her "'you are set free from your infirmity'" (Lk 13:12). "Then he put his hands on her, and immediately she straightened up and praised God" (:13). Then after the resurrection Jesus told them "'these signs will accompany those who believe'" (Mk 16:17). "'They will place their hands on sick people, and they will get well'" (:18). The father of the chief official of Malta was ill. On Paul's visit "after prayer, [he] placed his hands on him and healed him" (Ac 28:8). We can surmise that the miracles God did through the apostles (5:12), Stephen (6:8), and Paul (19:11) were accomplished by the laying on of hands.
