“On the Sabbath,

Jesus began to teach

In the synagogue.

Many who heard him

Were astonished.

They said.

‘Where did this man

Get all this?

What is this wisdom

That has been given

To him?

What deeds of power

Are being done

By his hands!’”

 

καὶ γενομένου σαββάτου ἤρξατο διδάσκειν ἐν τῇ συναγωγῇ· καὶ οἱ πολλοὶ ἀκούοντες ἐξεπλήσσοντο λέγοντες Πόθεν τούτῳ ταῦτα, καὶ τίς ἡ σοφία ἡ δοθεῖσα τούτῳ; καὶ αἱ δυνάμεις τοιαῦται διὰ τῶν χειρῶν αὐτοῦ γινόμεναι;

 

This story of Jesus astonishing the people in Nazareth can be found in all 3 synoptic gospels, here, Matthew, chapter 13:54-56, and Luke, chapter 4:16-22.  Luke was more elaborate, while Matthew was closer to Mark, who said that on the Sabbath (καὶ γενομένου σαββάτου), Jesus began to teach the people in the synagogue (ἤρξατο διδάσκειν ἐν τῇ συναγωγῇ).  However, many of the people that heard him were amazed or astonished (καὶ οἱ πολλοὶ ἀκούοντες ἐξεπλήσσοντο).  They wondered where did he get all this knowledge and wisdom (λέγοντες Πόθεν τούτῳ ταῦτα, καὶ τίς ἡ σοφία ἡ δοθεῖσα)?  Who gave him the power to do all these miraculous actions with his hands (καὶ αἱ δυνάμεις τοιαῦται διὰ τῶν χειρῶν αὐτοῦ γινόμεναι)?  They seemed surprised that Jesus was so smart and had these healing powers.  They would have known him for some time before this event.
