“And going on from thence, he saw other two brethren, James the son of Zebedee, and John his brother, in a ship with Zebedee their father, mending their nets; and he called them.”
King James Version (KJV)
Mt 4:21 Saw other two brethren. James and John, the sons of Zebedee. They were fishermen also, are supposed to have been cousins of Jesus, probably were already disciples (Joh 1:29-42), but were now called to preparation for their great work. In a ship. A small fishing vessel. The Revised Version says, "boat", which gives the idea.
