Q. Where in the gospels did yeshua jesus teach the law?

A. John 7:1 phbt After these things, Yeshua was walking in Galilee, for he did not want to walk in Judea, because the Judeans were seeking to kill him.
2 And the Jewish Feast of Tabernacles was near.
3 And his brothers said to Yeshua :"Remove yourself from here and go to Judea, that your disciples may see the works that you do."
4 For no man does anything in secret and wants it done openly. If you are doing these things, show yourself to the world.
5 For his brothers also did not believe in Yeshua.
6 Yeshua said to them: "My time has not yet come, but your time is always ready."
7 The world cannot hate you, but it hates me because I am testifying about it, that its servants are evil.
8 You go up to this feast; I am not going up now to this feast, because my time is not yet finished.
9 He said these things and he remained in Galilee.
10 But when his brothers went up to the feast, then he also went up, not openly, but as secretly.
11 But the Judeans were seeking him in the feast and they were saying, "Where is he?"
12 And there was much murmuring in the crowd because of him, for there were those who said, "He is good", and others were saying, "No, but he deceives the people."
13 But no man spoke openly about him, for fear of the Judeans.
14 But when the midpoint of the feast had arrived, Yeshua came up to The Temple and he taught.
15 And the Judeans were astonished and were saying, "How does this man know the scrolls, having not learned?"
16 Yeshua answered and said: "My teaching is not Mine, but from him who sent Me."
17 Whoever is willing to do his will understands my teaching, whether it is from God or whether I speak for my own pleasure.

So yeshua taught the torah scrolls without reading them from paper, but by the spirit of holiness.

People say that the bible should say that yeshua taught or read the law, if we have to follow it today. In john 7:14-15 the people who Heard yeshua speak at the feast of tabrinacles were asking how yeshua is able to quote/teach the scrolls without being taught. The answer is because he taught the teaching of the father. And we must be willing to follow the teaching from the scrolls as verse 17 says and matthew 4:4 & 23:1-3.

So yeshua taught the scrolls, without having the scrolls, and said it is the father's will to do it, to obey those who set on the throne of moshay, and men must live by every word that proceeds from the mouth of yahovah.
