“All spoke well of him.

They were amazed

At the gracious words

That came

From his mouth.

They said.

‘Is not this Joseph’s son?’”

 

καὶ πάντες ἐμαρτύρουν αὐτῷ καὶ ἐθαύμαζον ἐπὶ τοῖς λόγοις τῆς χάριτος τοῖς ἐκπορευομένοις ἐκ τοῦ στόματος αὐτοῦ, καὶ ἔλεγον Οὐχὶ υἱός ἐστιν Ἰωσὴφ οὗτος;

 

This story of Jesus astonishing the people in Nazareth can be found in all 3 synoptic gospels, Mark, chapter 6:2, and Matthew, chapter 13:54, and Luke here.  Luke said that all the people in the synagogue spoke well or testified in favor of Jesus (καὶ πάντες ἐμαρτύρουν αὐτῷ).  They were amazed at the gracious words (καὶ ἐθαύμαζον ἐπὶ τοῖς λόγοις τῆς χάριτος) that came from his mouth (τοῖς ἐκπορευομένοις ἐκ τοῦ στόματος αὐτοῦ).  At first, they were excited about how good Jesus was.  Then they said (καὶ ἔλεγον) was he not Joseph’s son (Οὐχὶ υἱός ἐστιν Ἰωσὴφ οὗτος)?  Thus, they were astonished and wondered where did he get all his wisdom.  They seemed surprised that Jesus was so smart or so important.  They would have known him for some time as merely the son of Joseph in Nazareth.
