Ezra 7:10, 25

For Ezra had set his heart to seek the law of Jehovah, and to do it, and to teach in Israel statutes and ordinances.

And thou, Ezra, after the wisdom of thy God that is in thy hand, appoint magistrates and judges, who may judge all the people that are beyond the River, all such as know the laws of thy God; and teach ye him that knoweth them not.
