And his sisters, are they not all with us? Whence then hath this man all these things?

People's New Testament

13:55,56 Is not this the carpenter's son? Joseph. Jesus was a carpenter also (Mr 6:3).

His mother called Mary? She is named. Joseph is indicated by his trade.

His brethren, James, and Joses, Simon, and Judas? Sons of Joseph and Mary. For a full discussion of their relationship, see PNT Joh 2:12.

Jamieson-Fausset-Brown Bible Commentary

56. And his sisters, are they not all with us? Whence then hath this man all these things? An exceedingly difficult question here arises-What were these "brethren" and "sisters" to Jesus? Were they, First, His full brothers and sisters? or, Secondly, Were they His step-brothers and step-sisters, children of Joseph by a former marriage? or, Thirdly, Were they cousins, according to a common way of speaking among the Jews respecting persons of collateral descent? On this subject an immense deal has been written, nor are opinions yet by any means agreed. For the second opinion there is no ground but a vague tradition, arising probably from the wish for some such explanation. The first opinion undoubtedly suits the text best in all the places where the parties are certainly referred to (Mt 12:46; and its parallels, Mr 3:31; Lu 8:19; our present passage, and its parallels, Mr 6:3; Joh 2:12; 7:3, 5, 10; Ac 1:14). But, in addition to other objections, many of the best interpreters, thinking it in the last degree improbable that our Lord, when hanging on the cross, would have committed His mother to John if He had had full brothers of His own then alive, prefer the third opinion; although, on the other hand, it is not to be doubted that our Lord might have good reasons for entrusting the guardianship of His doubly widowed mother to the beloved disciple in preference even to full brothers of His own. Thus dubiously we prefer to leave this vexed question, encompassed as it is with difficulties. As to the names here mentioned, the first of them, "James," is afterwards called "the Lord's brother" (see on [1298]Ga 1:19), but is perhaps not to be confounded with "James the son of Alphæus," one of the Twelve, though many think their identity beyond dispute. This question also is one of considerable difficulty, and not without importance; since the James who occupies so prominent a place in the Church of Jerusalem, in the latter part of the Acts, was apparently the apostle, but is by many regarded as "the Lord's brother," while others think their identity best suits all the statements. The second of those here named, "Joses" (or Joseph), must not be confounded with "Joseph called Barsabas, who was surnamed Justus" (Ac 1:23); and the third here named, "Simon," is not to be confounded with Simon the Kananite or Zealot (see on [1299]Mt 10:4). These three are nowhere else mentioned in the New Testament. The fourth and last-named, "Judas," can hardly be identical with the apostle of that name-though the brothers of both were of the name of "James"-nor (unless the two be identical, was this Judas) with the author of the catholic Epistle so called.

Matthew Henry's Concise Commentary

13:53-58 Christ repeats his offer to those who have repulsed them. They upbraid him, Is not this the carpenter's son? Yes, it is true he was reputed to be so; and no disgrace to be the son of an honest tradesman; they should have respected him the more because he was one of themselves, but therefore they despised him. He did not many mighty works there, because of their unbelief. Unbelief is the great hinderance to Christ's favours. Let us keep faithful to him as the Saviour who has made our peace with God.
