When he entered Capernaum, a centurion came forward to him, appealing to him, “Lord, my servant is lying paralyzed at home, suffering terribly.” And he said to him, “I will come and heal him. . .” And to the centurion Jesus said, “Go; let it be done for you as you have believed.” And the servant was healed at that very moment. Matthew 8:5-7, 13
Then came one of the rulers of the synagogue, Jairus by name, and seeing him, he fell at his feet and implored him earnestly, saying, “My little daughter is at the point of death. Come and lay your hands on her, so that she may be made well and live.” And he went with him. . . Taking her by the hand he said to her, “Talitha cumi,” which means, “Little girl, I say to you, arise.” And immediately the girl got up and began walking (for she was twelve years of age), and they were immediately overcome with amazement. Mark 5:22-24, 41-42
