Malachi 2:5-7

Darby(i) 5 My covenant with him was of life and peace, and I gave them to him that he might fear; and he feared me, and trembled before my name. 6 The law of truth was in his mouth, and unrighteousness was not found in his lips: he walked with me in peace and uprightness, and he turned many from iniquity. 7 For the priest`s lips should keep knowledge, and at his mouth they seek the law; for he is the messenger of Jehovah of hosts.
