Albert Barnes Commentary Matthew 13:54

"And coming into his own country he taught them in their synagogue, insomuch that they were astonished, and said, Whence hath this man this wisdom, and these mighty works?" — Matthew 13:54 (ASV)

Into his own country. That is, into Nazareth. Mark, who has also recorded this (Mark 6:1–6), says that it took place on the Sabbath. It was common for our Saviour to speak in the synagogues. Any Jew had a right to address the people, if called on by the minister; and our Saviour often availed himself of the right to instruct the people, and declare his doctrines. See Matthew 4:23.
