'Kneading troughs' in the Bible

And the river shall bring forth frogs abundantly, which shall go up and come into your house, and into your bedchamber, and upon your bed, and into the house of your servants, and upon your people, and into your ovens, and into your kneading troughs:

And the people took their dough before it was leavened, their kneading troughs being bound up in their clothes upon their shoulders.
