“They were astonished
At his teaching,
Because he spoke
καὶ ἐξεπλήσσοντο ἐπὶ τῇ διδαχῇ αὐτοῦ, ὅτι ἐν ἐξουσίᾳ ἦν ὁ λόγος αὐτοῦ
Luke said that they were astonished (καὶ ἐξεπλήσσοντο) at his teaching (ἐπὶ τῇ διδαχῇ αὐτοῦ), because he spoke with authority (ὅτι ἐν ἐξουσίᾳ ἦν ὁ λόγος αὐτοῦ). There is something similar to this in Mark, chapter 1:22, and Matthew, chapter 7:29, where Jesus was teaching with authority. Mark said, just like Luke, word for word, that the people of this Capernaum synagogue were amazed at his teaching since he taught them as if he had authority. However, Mark added that he was not like one of the Scribes, who were religious experts that determined the traditions to be followed. Matthew, chapter 7:29, said that this amazing Jesus taught on his own authority without referring to tradition. What was this authority that Jesus had?
