Malachi 2:8-14 AMP

8 But you have turned aside out of the way; you have caused many to stumble by your instruction [in the law]; you have corrupted the covenant of Levi [with Me], says the Lord of hosts.

9 Therefore have I also made you despised and abased before all the people, inasmuch as you have not kept My ways but have shown favoritism to persons in your administration of the law [of God].

10 Have we not all one Father? Has not one God created us? Why then do we deal faithlessly and treacherously each against his brother, profaning the covenant of [God with] our fathers?

11 Judah has been faithless and dealt treacherously, and an abomination has been committed in Israel and in Jerusalem; for Judah [that is, Jewish men] has profaned the holy sanctuary of the Lord which He loves, and has married the daughter of a foreign god [having divorced his Jewish wife]. [Ezra 9:2; Jer. 2:3.]

12 The Lord will cast out of the tents of Jacob to the last man those who do this [evil thing], the master and the servant [or the pupil] alike, even him who brings an offering to the Lord of hosts.

13 And this you do with double guilt; you cover the altar of the Lord with tears [shed by your unoffending wives, divorced by you that you might take heathen wives], and with [your own] weeping and crying out because the Lord does not regard your offering any more or accept it with favor at your hand.

14 Yet you ask, Why does He reject it? Because the Lord was witness [to the covenant made at your marriage] between you and the wife of your youth, against whom you have dealt treacherously and to whom you were faithless. Yet she is your companion and the wife of your covenant [made by your marriage vows].
