Mark 6:2

ἤρξατο διδάσκειν, etc.: Jesus did not go to Nazareth for the purpose of preaching, rather for rest; but that He should preach was inevitable; therefore, the Sabbath coming round, He appeared in the synagogue, and spoke. πόθεν τούτῳ ταῦτα : laconic; comprehensive, vague question, covering the discourse just heard and all that had been reported to them about their townsman, with the one word ταῦτα : such speech, such wisdom (τίς ἡ σοφία), such powers (δυνάμεις, not wrought there), in such a well-known person (τούτῳ).
