Is not this man the carpenter's son? Is not his mother called Mary? Are not his brothers James, Joseph, Simon, and Judas?

The crowd uses these questions to express their belief that they know who Jesus is and that he is just an ordinary man. Alternate translation: "He is just the son of a carpenter. We know his mother Mary, and his brothers James, Joseph, Simon, and Judas." (See: rc://en/ta/man/translate/figs-rquestion)

the carpenter's son

A carpenter is someone who makes things with wood or stone. If "carpenter" is not known, "builder" can be used.
