Maleachi 2:8

Mal 2:8. "But ye have departed from the way, have made many to stumble at the law, have corrupted the covenant of Levi, saith Jehovah of hosts. Mal 2:9. Thus I also make you despised and base with all the people, inasmuch as ye do not keep my ways, and respect person in the law." הדּרך is the way depicted in Mal 2:6 and Mal 2:7, in which the priests ought to have walked. הכשׁלתּם בּתּורה does not mean "ye have caused to fall by instruction" (Koehler); for, in the first place, hattōrâh (with the article) is not the instruction or teaching of the priests, but the law of God; and secondly, ב with כּשׁל denotes the object against which a man stumbles and which causes him to fall. Hitzig has given the correct explanation: ye have made the law to many a מכשׁול, instead of the light of their way, through your example and through false teaching, as though the law allowed or commanded things which in reality are sin. In this way they have corrupted or overthrown the covenant with Levi. הלּוי, with the article, is not the patriarch Levi, but his posterity, really the priesthood, as the kernel of the Levites. Hence Jehovah also is no longer bound by the covenant, but withdraws from the priests what He granted to the Levi who was faithful to the covenant, viz., life and salvation (Mal 2:5), and makes them contemptible and base with all the people. This is simply a just retribution for the fact, that the priests depart from His ways and have respect to men. Battōrâh, in the law, i.e., in the administration of the law, they act with partiality. For the fact itself compare Mic 3:11.

There are two great ordinances which divine wisdom has instituted, the wretched profanation of both of which is complained of and sharply reproved in this chapter. I. The ordinance of the ministry, which is peculiar to the church, and is designed for the maintaining and keeping up of that; this was profaned by those who were themselves dignified with the honour of it and entrusted with the business of it. The priests profaned the holy things of God; this they are here charged with; their sin is aggravated, and they are severely threatened for it (Mal 2:1-9). II. The ordinance of marriage, which is common to the world of mankind, and was instituted for the maintaining and keeping up of that; this was profaned both by the priests and by the people, in marrying strangers (Mal 2:11, Mal 2:12), treating their wives unkindly (Mal 2:13), putting them away (Mal 2:16), and herein dealing treacherously (Mal 2:10, Mal 2:14, Mal 2:15). And that which was at the bottom of this and other instances of profaneness and downright atheism, thinking God altogether such a one as themselves, which was, in effect, to say, There is no God (Mal 2:17). And these reproofs to them are warnings to us.
