Malachi 2:6; Malachi 2:7; Malachi 2:9

6 The law of truth was in his mouth, and iniquity was not found in his lips: he walked with me in peace and equity, and did turn many away from iniquity.

7 For the priest's lips should keep knowledge, and they should seek the law at his mouth: for he is the messenger of the LORD of hosts.

9 Therefore have I also made you contemptible and base before all the people, according as ye have not kept my ways, but have been partial in the law.
