Daughter of a strange god - Of a man who worships an idol.
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 the holiness of the Lord which He loved - , in themselves, who had been separated and set apart by God to Himself as a Exodus 19:6. “holy nation. Jeremiah 2:3. Israel was holiness to the Lord.” “The Lord is holy, perfect holiness; His name, holy; all things relating to Him, holy; His law, covenant and all His ordinances and institutions holy; Israel, His special people, an holy people; the temple and all things therein consecrated to Him, holy; Jerusalem, the city of the great God, holy; yea, the whole and of His inheritance, holy; so that whosoever doth not observe those due respects which to any of these belong, may be said to have profaned the holiness which He loved.”
Unlawful marriages and unlawful lusts were in themselves a special profanation of that holiness. The high priest was to Leviticus 21:14-15, “take a virgin of his own people to wife, and not to profane his seed among the people.” The priests who “married stranqe wives, defiled the priesthood and the covenant of the priesthood” Nehemiah 13:29. The marriage with idolatresses brought, as one consequence, the profanation by their idolatries. The prohibition is an anticipation of the fuller revelation in the Gospel, that 1 Corinthians 6:15-20 the body is the temple of the Holy Spirit, and so, that “sins against the body” are profanations of the temple of God. “As those who acknowledge, worship and serve the true God are called His Deuteronomy 32:19; 2 Corinthians 6:18 sons and daughters, so they that worshiped any strange god are, by like reason, here called the daughters of that god. Hence, the Jews say, ‹He that marrieth a pagan woman is, as if he made himself son-in-law to an idol. ‹“
Hath married the daughter of a strange god - And so he came into closest relation with idols and with devils.
