Leviticus 26:26
When I cut off your supply of bread, ten women will bake your bread in a single oven and dole out your bread by weight, so that you will eat but not be satisfied.
Hosea 7:4–7
They are all adulterers, like an oven heated by a baker who needs not stoke the fire from the kneading to the rising of the dough. / The princes are inflamed with wine on the day of our king; so he joins hands with those who mock him. / For they prepare their heart like an oven while they lie in wait; all night their anger smolders; in the morning it blazes like a flaming fire.
