Verse 18 James the son of Alpheus. His father's name is given to distinguish him from the other James, the son of Zebedee. In theological writings, the former is generally called James the greater, and the latter James the less. James the less is supposed to have written the Epistle called by his name.--Simon the Canaanite. He is called by Luke 6:15, Simon Zelotes. He is thus particularly designated to distinguish him from Simon Peter.
