Ezra 7:10, 25

For Ezra had set his heart to study the Law of the LORD, and to do it and to teach his statutes and rules in Israel.

“And you, Ezra, according to the wisdom of your God that is in your hand, appoint magistrates and judges who may judge all the people in the province Beyond the River, all such as know the laws of your God. And those who do not know them, you shall teach.
