Three years before Christ gave his life Jewish synagogue audiences were began having the time of their lives. Mark 6:2 gives a recurring slice of Yeshua’s life: he began to teach. We know when he stopped.
And when the sabbath day was come, he began to teach in the synagogue: and many hearing him were astonished, saying, From whence hath this man these things? and what wisdom is this which is given unto him, that even such mighty works are wrought by his hands?Mark 6:2
Astonishing describes the content of Yeshua’s teaching. “Where did he get these things?” is not a serious source question. He did not plagiarize and he did not recite Torah like a robot.
Wisdom describes the soundness of Yeshua’s teaching. “What wisdom is this” is an exclamation of recognition. Wisdom cannot be hidden and no one ever said “what a fool that rabbi from Nazareth is!” Yeshua was a vetted sage since age 12.
Mighty establishes the majestic witness of Yeshua’s work. They could not be separated from his hands. There was no mistake that things thought impossible and things people waited for all their lives were happening at his command.
