The apostle John, son of Zebedee and, it seems, Salome (compare Mt 27:55, 56; Mr 15:40) and brother of the apostle James—likely James’ younger brother, as James is usually named first where both are mentioned. (Mt 10:2; Mr 1:19, 29; 3:17; 10:35, 41; Lu 6:14; 8:51; 9:28; Ac 1:13)
... Peter, James, and John were taken to the mountain of transfiguration. (Mt 17:1, 2; Mr 9:2; Lu 9:28, 29)
