Hosea 7:4

They are all adulterers, both spiritually and carnally, and this latter adultery is that which here is charged on the courtiers and people of Israel. As an oven heated by the baker: this vice is grown raging hot among them, as you see the fire in an oven, when the baker, having called up those that make the bread, to prepare all things ready, and the whole mass is leavened, he doth by continued supply of fuel heat the oven to the highest degree. So doth adultery among this people grow by degrees to raging flames. The whole mass of the people are leavened with this vice also, as well as the court, and every one inflamed with this unclean fire, as the oven heated by the baker.
