James, son of Zebedee, was one of the Twelve Apostles of Jesus. He was a son of Zebedee and Salome, and brother of John the Apostle. He is also called James the Greater to distinguish him from James, son of Alphaeus, who is also known as James the Less. James is described as one of the first disciples to join Jesus. The Synoptic Gospels state that James and John were with their father by the seashore when Jesus called them to follow him. According to the Gospel of Mark, James and John were called Boanerges, or the "Sons of Thunder".[Mark 3:17] James was one of only three apostles whom Jesus selected to bear witness to his Transfiguration. The Acts of the Apostles records that Agrippa I had James executed by sword, making him the first of the apostles to be martyred.
