Malachi 2:7

2:7 For the lips of a priest should preserve knowledge of sacred things, and people should seek instruction from him because he is the messenger of the Lord who rules over all.

Malachi 2:15

2:15 No one who has even a small portion of the Spirit in him does this. What did our ancestor do when seeking a child from God? Be attentive, then, to your own spirit, for one should not be disloyal to the wife he took in his youth.
