Jesus had brothers and sister but no mention of this is made

Jesus childhood home is identified in the gospels of Luke and Matthew as the town of Nazareth in Galilee. Mary’s husband Joseph appears in descriptions of Jesus’ childhood, but no mention is made of him thereafter. His family members—his mother, Mary, his brothers James, Joses (or Joseph), Judas and Simon and his unnamed sisters—are mentioned in the gospels and other sources. Some early Christian writers, concerned that mention of Jesus’ brothers and sisters contradicted the doctrine of the perpetual virginity of Mary, argued that these represented either older children of Joseph by a previous marriage, or that the reference was actually to “cousins”. Both interpretations are discounted by modern scholars.

Originally written in Koine Greek, the Gospel of Mark calls Jesus in Mark 6:3 a τέκτων (tekton), usually understood to mean a carpenter, and Matthew 13:55 says he was the son of a tekton. Although traditionally translated as “carpenter”, tekton is a rather general word (from the same root that leads to “technical” and “technology”) that could cover makers of objects in various materials, including builders. Beyond the New Testament accounts, the association of Jesus with woodworking is a constant in the traditions of Early Christianity. Justin Martyr wrote that Jesus made yokes and ploughs. The gospels indicate that Jesus could read, paraphrase, and debate scripture, but this does not imply that he received formal scribal training.
