Malachi 2:10

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.

8 But ye have departed out of the way; ye have caused many to stumble at the law; ye have corrupted the covenant of Levi, saith 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.

10 Have we not all one father? hath not one God created us? why do we deal treacherously every man against his brother, by profaning the covenant of our fathers?

11 Judah hath dealt treacherously, and an abomination is committed in Israel and in Jerusalem; for Judah hath profaned the holiness of the LORD whom he loved, and hath married the daughter of a strange god.

12 The LORD will cut off the man that doeth this, the master and the scholar, out of the tabernacles of Jacob, and him that offereth an offering to the LORD of hosts.

13 And this have ye done again, covering the altar of the LORD with tears, with weeping, and with crying out, insomuch that he regardeth not the offering any more, or receiveth [it] with good will at your hand.
