They are all adulterers. They are burning like an oven that the baker stops stirring, From the kneading of the dough, until it is leavened.
But a third thing follows, and that is, that this fire had not been suddenly lighted up, but had been for a long time gathering strength. Hence he says As an oven heated by the baker, who ceases, he says, from stirring up after the shaking or mixing of the meal, until it be fermented לום, lush, means “to besprinkle,” empaster is what they say here. Some foolishly hold that they were like those who sleep and afterwards awake early in the morning. But the Prophet had a different thing in view, and that was, that by length of time their wickedness had increased, and, as it were, by degrees. He means, in short, that they had not been under a sudden impulse, like men who often break out through want of thought, and immediately repent; and their lust, which had been in a moment set on fire, in a short time abates. The Prophet says, that the frenzy of the people of Israel had been different; for they had been like an oven, which the baker, after having lighted up, allows to grow quite hot even to the highest degree; for he waits while the dough is becoming well fermented. It was not then the intemperance and lust of a few days; but they made their hearts quite hot, as when a baker heats his oven, and puts in a great quantity of fuel, that after a time it may become heated, while the dough is fermenting.
