Malachi 2:11

“Judah hath dealt treacherously, etc.] Not only every man against his brother, by being partial in the law; or against the women of their nation, by marrying others; or against their wives, by putting them away; but against Christ the Son of God by betraying and delivering him up into the hands of the Gentiles, to be mocked, and scourged, and crucified: and an abomination is committed in Israel, and in Jerusalem; which was the taking of the true Messiah with wicked hands, condemning him and putting him to death, even the shameful and accursed death of the cross; which was done in the land of Israel, and in and near the city of Jerusalem: for Judah hath profaned the holiness of the Lord, which…”

“dealt treacherously--namely, in respect to the Jewish wives who were put away (Mal 2:14; also Mal 2:10, Mal 2:15-16). profaned the holiness of . . . Lord--by ill-treating the Israelites (namely, the wives), who were set apart as a people holy unto the Lord: "the holy seed" (Ezr 9:2; compare Jer 2:3). Or, "the holiness of the Lord" means His holy ordinance and covenant (Deu 7:3). But "which He loved," seems to refer to the holy people, Israel, whom God so gratuitously loved (Mal 1:2), without merit on their part (Psa 47:4). married, &c.-- (Ezr 9:1-2; Ezr 10:2; Neh 13:23, &c.). daughter of a strange god--women worshipping idols: as the worshipper in Scripture is regarded in the relation of a…”

“Treacherously has Judah dealt; an abomination is committed in Israel - The prophet, by the order of the words, emphasizes the “treachery” and the “abomination.” This have they done; the very contrary to what was required of them as the people of God. He calls the remnant of Judah by the sacred name of the whole people, of whom they were the surviving representatives. The word “abomination” is a word belonging to the Hebrew, and is used especially of things offensive to, or separating from, Almighty God; idolatry, as the central dereliction of God, and involving offences against the laws of nature, but also all other sins, as adultery, which violate His most sacred laws and alienate from Him.…”

“Hath profaned - Profanely violated the law, confining Israel to marry within themselves, and not to endanger themselves, by contracting affinity with idolaters. Which he loved - Which he, Judah, once loved. The daughter - Idolatresses. Even tho' they had wives before, whom they now cast off. Malachi 2:12”

“2:11 Judah has been unfaithful (or treacherous), and a detestable thing has been done in Israel and in Jerusalem: Men were divorcing their wives for the economic advantage of intermarriage with non-Israelite women who worshiped idols. Through these marriages, Jewish men gained access to the merchant guilds and trading cartels already in place when the Israelites returned from Babylonia. Malachi equates this adultery with idolatry. Israelite history had shown that intermarriage with foreign women went hand in hand with worship of foreign gods. Loyalty was to be the hallmark of Israel’s covenant relationships, whether with God or with a marriage partner. Divorce treats with contempt the…”
