3. Adultery and uncleanness prevailed much among the courtiers. This is spoken of v. 4, 6, 7, and the charge of drunkenness comes in in the midst of this article; for wine is oil to the fire of lust, Prov. xxiii. 33. Those that are inflamed with fleshly lusts, that are adulterers (v. 4), are here again and again compared to an oven heated by the baker (v. 4): They have made ready their heart like an oven (v. 6); they are all hot as an oven, v. 7. Note, (1.) An unclean heart is like an oven heated; and the unclean lusts and affections of it are as the fuel that makes it hot. It is an inward fire, it keeps the heat within itself; so adulterers and fornicators secretly burn in lust, as the expression is, Rom. i. 27. The heat of the oven is an intense heat, especially as it is here described; he that heats it stirs up the fire, and ceases not from raising it up, till the bread is ready to be put in, being kneaded and leavened, all which only signifies that they are like an oven when it is at the hottest; nay, when it is too hot for the baker (so the learned Dr. Pocock), when it is hotter than he would have it, so that the raiser up of the fire ceases as long as while the dough that is kneaded is in the fermenting, that the heat may abate a little. Thus fiery hot are the lusts of an unclean heart. (2.) The unclean wait for an opportunity to compass their wicked desires; having made ready their heart like an oven, they lie in wait to catch their prey. The eye of the adulterer waits for the twilight, Job xxiv. 15. Their baker sleeps all the night, but in the morning it burns as a flaming fire. As the baker, having kindled a fire in his oven and laid sufficient fuel to it, goes to bed, and sleeps all night, and in the morning finds his oven well heated, and ready for his purpose, so these wicked people, when they have laid some wicked plot, and formed a design for the gratifying of some covetous, ambitious, revengeful, or unclean lusts, have their hearts so fully set in them to do evil that, though they may stifle them for a while, yet the fire of corrupt affections is still glowing within, and, as soon as ever there is an opportunity for it, their purposes which they have compassed and imagined break out into overt acts, as a fire flames out when it has vent given it. Thus they are all hot as an oven. Note, Lust in the heart is like fire in an oven, puts it into a heat; but the day is coming when those who thus make themselves like a fiery oven with their own vile affections, if that fire be not extinguished by divine grace, shall be made as a fiery oven by divine wrath (Ps. xxi. 9), when the day comes that shall burn as an oven, Mal. iv. 1.
