And thou, Ezra, after the wisdom of thy God, that is in thine hand,.... Which he had a large share of from the Lord, and could readily make use of to good purpose; and this may be meant of the law of God made with the highest wisdom, and to know and observe which is an instance of wisdom in men, De 4:6,set magistrates and judges, which may judge all the people that are beyond the river, all such as know the laws of thy God; such as God, in his great wisdom, directed to in his wise law to be appointed over the people, to judge righteous judgment; to inform them in all matters of controversy that might arise among them, and decide them according to it; and lead them into a greater and better knowledge of it, De 16:18.
Jarchi takes the word for "set" to be a comparative, and the sense to be, that the wisdom of Ezra was greater than the judges that judged the people, than them that knew the law:and teach ye them that know them not; such people that were ignorant thereof; though the above writer interprets this of ignorant judges,"the judge that knows not to judge, make him know judgment to do it.'
