Hosea 7:4

They [are] all adulterers, as an oven heated by the baker, [who] ceaseth from raising after he hath kneaded the dough, until it be leavened.

Ver. 4. They are all adulterers] εξεκαυσθησαν, adulterio caleseunt, so Paguine, scalded in their base lusts, as those in Romans 1:27, all (for the most part) were such; but especially the courtiers and clawback informers, as Hosea 7:3, God, in his just judgment, giving them up to those vile affections or passions of dishonour, and punishing their impieties with impurities, as he did also in those heathens, Romans 1:23 .

As an oven heated by the baker] An apt similitude setting forth the intense heat of filthy lust (better marry than burn, 1Co 7:9), and of long continuance as the heat of an oven; yea, of Nebuchadnezzar's oven, yea, of hell itself, whence it was enkindled, and where it shall be perpetually punished. The holy angels at the last day will be most active against such, to bring them to condign punishment: 2 Peter 2:10, "But chiefly them that walk after the flesh in the lust of uncleanness." Note the word chiefly, and consider the example of the Sodomites, and God most severe against them, Hebrews 13:4. How much they have lived deliciously, and drenched themselves in fleshly delights, so much torments and sorrow shall they have proportionably, Revelation 18:7. As their hearts have been as a hot oven or furnace, so they shall be bound up in bundles, and cast into a furnace of fire, where shall be wailing and gnashing of teeth, Matthew 13:42 .
