Verses 12-19:
Israel’s Idolatry Enlarged
Verse 12 describes how Israel, the Northern Kingdom had, and were expanding, their idolatrous course by seeking council of wooden gods (stocks). They leaned on a staff of wooden gods, expanding their idolatrous worship, leaving the authority of worship of Jehovah. Their stocks were wooden idols, Jeremiah 2:27; Habakkuk 2:19. Their staff (wooden rods) they had leaned on, and consulted, as a form of divination, Ezekiel 21:21-22. Thus they went further astray (erred) from the true God, Hosea 5:4. Their going a "whoring from under their God", is abhorrently compared with a woman who goes a whoring from under the dominion of and duties to her husband.
Verse 13 recounts the custom of worshipping wooden idols, built on high hills and mountains, thought to be nearer to God and the heavenly hosts they sought to worship, Deuteronomy 12:2. This they did under the shade of oaks, poplars, and elms, to screen their lascivious deeds from the sun, Isaiah 1:29; Isaiah 57:5; Isaiah 57:7; Ezekiel 6:13; Ezekiel 20:28. As a result of the obstinate lustful will of the parents, and their idolatrous deeds, their daughters and their spouses were to be delivered up to vile affections and deeds, as a punishment for their idolatry, bringing shame upon the whole family name, Amos 7:17; Romans 1:28.
Verse 14 asserts that God will not send the heaviest punishment upon the daughters of Israel and their spouses but upon the fathers and husbands, the elders of the people. Because their fathers had come to the idol altars to be with harlots, not their wives. The young are not to be so much blamed, when their fathers are much worse, as they engage in whoredom with the consecrated harlots available at the altars of Ashtaroth and Astarte, that were prevalent in Syria, Assyria, Phoenecia, Phrygia, and Babylon, Numbers 15:1-3; Deuteronomy 23:18; Isaiah 44:18; Isaiah 45:20.
Verses 15-19 constitute a warning to Judah, the southern kingdom, not to become partakers of Israel’s harlotry, guilt, and offense. Israel is warned not to make pilgrimages to places of idolatrous worship. For Judah had the legal priesthood, the temple rites, and had Jerusalem as her center. Gilgal, a former holy place in the days of Samuel, located between Jericho and the Jordan river, on the border of Samaria, had now become a place of wickedness and graven images from which Judah was to keep himself, Joshua 5:4-7; Joshua 5:10-15; 1 Samuel 10:8; 1 Samuel 15:21; Hosea 9:15; Hosea 12:11; Amos 5:5; Judges 3:19. They were warned not to go up to Beth-aven "the house of idols" or of vanity, rather than to Bethel "the house of God." To swear is forbidden, in conjunction with calf-worship or idolatry, because such is contemptible to God, Ezekiel 20:39; Zephaniah 1:5.
Verse 16 describes Israel’s continual backsliding or instability that is like a heifer that throws the yoke off her neck, Jeremiah 7:24. She is untamed, undisciplined, disinclined to wear God’s yoke and do His service in truth, 1 Kings 12:28. God will feed Israel like a lamb in a large fenced enclosure. He will feed them with the rod, while at the same time chastening them in their Assyrian exile, Micah 7:14; Jeremiah 3:6; Jeremiah 8:5; Zechariah 7:11.
Verse 17 asserts that Ephraim glued to his idols, as an whoremonger in idol worship, is to be left alone to his chosen destiny, here representing the ten northern tribes, Numbers 15:3; 1 Corinthians 6:16-17; let him reap the fruits of his own choice, Jeremiah 7:16; Isaiah 48:20; 2 Corinthians 6:17; Matthew 15:14.
Verse 18 describes their drink as "sour", signifying the degeneracy of licentiousness, Isaiah 1:22. They were like drunks who vomit and smell sour from it, and when their drinking was over they committed whoredoms with Astarte, the idol, or in honor of her, a debauching form of worship, v. 13, 14. The rulers, shields and protectors of the state of Israel, sold justice for shame, winked at moral wickedness, for personal covetous gain, Proverbs 30:15; This was much as Esau who sold his birthright for a mess of pottage. There exists no internal remedy for corruption when rulers are bribed, Hebrews 12:16-17; Genesis 25:33.
Verse 19 describes adulterous, idolatrous Israel as one suddenly surrounded, bound up and seized by a violent tempest and carried far away from their land for destruction and shame, Psalms 18:19; Psalms 104:3; Isaiah 57:13; Jeremiah 4:11-12. They shall come to be ashamed of their idols, and disappointed in hope of help through their idols, as a fruit of their willful disregard for the very fundamental A.B.C.’s of their own religious laws, Exodus 20:1-5.
