Yes we DO know:
14 Now Jesus returned in the power of the spirit into Galʹi·lee. And good reports about him spread throughout all the surrounding country. 15 Also, he began to teach in their synagogues, and he was held in honor by all.
16 He then went to Nazʹa·reth, where he had been brought up, and according to his custom on the Sabbath day, he entered the synagogue and stood up to read. 17 So the scroll of the prophet Isaiah was handed to him, and he opened the scroll and found the place where it was written: 18 “Jehovah’s spirit is upon me, because he anointed me to declare good news to the poor. He sent me to proclaim liberty to the captives and a recovery of sight to the blind, to send the crushed ones away free, 19 to preach Jehovah’s acceptable year.” 20 With that he rolled up the scroll, handed it back to the attendant, and sat down; and the eyes of all in the synagogue were intently fixed on him. 21 Then he began to say to them: “Today this scripture that you just heard is fulfilled.”
