Mark 6:3

Is not this the carpenter? Save in this one place, our Lord is nowhere Himself called "the Carpenter." According to the custom of the Jews, even the Rabbis learnt some handicraft. One of their proverbs was that "he who taught not his son a trade, taught him to be a thief." Hence St Paul learnt to "labour with his own hands" at the trade of a tent-maker (Act 18:3; 1 Thessalonians 2:9; 1 Corinthians 4:12). "In the cities the carpenters would be Greeks, and skilled workmen; the carpenter of a provincial village could only have held a very humble position, and secured a very moderate competence." Farrar's Life of Christ, I. 81.

the brother of James, and Joses The four "brothers" here mentioned, and "the sisters," whose names are nowhere recorded, were in all probability the children of Clopas and Mary, the sister and namesake of the blessed Virgin, and so the "cousins" of our Lord. (Compare Matthew 27:56 with Mark 15:40 and John 19:25.) Joseph would seem to have died at some time between a. d. 8 and a. d. 26, and there is no reason for believing that Clopas was alive during our Lord's ministry. It has been suggested, therefore, that the two widowed sisters may have lived together, the more so as one of them had but one son, and He was often taken from her by His ministerial duties. Three other hypotheses have been formed respecting them: (1) that they were the children of Joseph by a former marriage; (2) that they were the children of Joseph and Mary; (3) that Joseph and Clopas being brothers, and Clopas having died, Joseph raised up seed to his dead brother, according to the Levirate law.
