'Troughs' in the Bible

[Now] the priest of Midian had seven daughters, and they came and drew water and filled the troughs to water their father's flock.

And the Nile will swarm with frogs, and they will go up and come into your house and into your {bedroom} and onto your bed and into the house of your servants and among your people and into your ovens and into your kneading troughs.

And the people lifted up their dough before it had yeast; their kneading troughs [were] wrapped up in their cloaks on their shoulder.
