“ He is enjoined, therefore, to attend to the teaching of the Law, that in accordance with the office committed to him, he may bring forward what he has learned for the common benefit of the people. At the same time he is ordered to make his own docility a pattern of obedience to others. For many, by talking and discoursing, have the Law in their mouth, but are very bad keepers of it. Both things, therefore, are commanded, that by teaching others, he may make his own conduct and whole character conformable to the same rule. ”
