Where did Jesus get his authority? (Mt 21:23-21:23)

“When Jesus entered

The Temple,

The chief priests

And the elders of the people

Came to him,

As he was teaching.

They said.

‘By what authority

Are you doing these things?

Who gave you

This authority?’”

 

Καὶ ἐλθόντος αὐτοῦ εἰς τὸ ἱερὸν προσῆλθον αὐτῷ διδάσκοντι οἱ ἀρχιερεῖς καὶ οἱ πρεσβύτεροι τοῦ λαοῦ λέγοντες Ἐν ποίᾳ ἐξουσίᾳ ταῦτα ποιεῖς; καὶ τίς σοι ἔδωκεν τὴν ἐξουσίαν ταύτην;

 

This questioning of the authority of Jesus can be found in Mark, chapter 11:27-28, and Luke, chapter 20:1-2, almost word for word.  When Jesus entered the Temple (Καὶ ἐλθόντος αὐτοῦ εἰς τὸ ἱερὸν), the chief priests (οἱ ἀρχιερεῖς) or the high priest with the presbyters or elders of the people (καὶ οἱ πρεσβύτεροι τοῦ λαοῦ) approached him as he was teaching (προσῆλθον αὐτῷ διδάσκοντι).  They wanted to know by what authority was he doing all these things (Ἐν ποίᾳ ἐξουσίᾳ ταῦτα ποιεῖς) in the Temple?  Who gave him his authority (καὶ τίς σοι ἔδωκεν τὴν ἐξουσίαν ταύτην;)?  This seemed like a legitimate question since Jesus was not a Levitical priest or an ordained rabbi.  They wanted to know where he came from and what he was trying to do.
