에스라 7:10 탈무드 참조: Jerusalem Talmud Sanhedrin & Avot DeRabbi Natan

It is written²¹¹There is no such verse in the Bible. The text is a combination of 2Chr. 30:19 and Ezra 7:10.: With all his heart he prepared himself to seek God, to act, and to teach law and justice in Israel. Rebbi Simon bar Zavdi and Rebbi Samuel bar Naḥman. One said, with all he did for the purity of the Temple, he did not fully establish the purity of the Temple. One said, with all the good works he did, he did not fully do his duty for the purity of the Temple. It is written²¹²2Chr. 29:16.: They started on the first of the first month, and on the eighth day they entered the Eternal’s Hall and sanctified the Eternal’s House for three days; on the sixteenth of the month they finished. Could they not have eliminated all idolatry from there in one day? Rebbi Idi said, because of Chaldean idols which were engraved in vermilion.

Make your Torah study a fixed practice. How so? This teaches us that if a person hears advice from the mouth of a sage in the study hall, he should not make it an occasional practice but a fixed practice. What a person learns, he should do, and then teach others, and they should do, as it says (Deuteronomy 5:1), “Learn them, and take care to do them.” And also in Ezra it says (7:10), “For Ezra had prepared his heart to seek the Torah of the Eternal and to do it.” And after that, it says, “and to teach Israel rules and laws.”
