'Watering troughs' in the Bible

And he set the rods which he had peeled over against the flocks in the gutters in the watering-troughs where the flocks came to drink; and they conceived when they came to drink.

Furthermore, whenever the stronger [animals] of the flocks were breeding, Jacob would place the branches in the sight of the flock in the watering troughs, so that they would mate and conceive among the branches;

And to the priest of Midian, seven daughters: and they will come and will draw and fill the watering troughs to water the sheep of their father.

From the voice of arrows between the watering-troughs, There will they give the justices of Jehovah, The justices of his rule in Israel: Then will the people of Jehovah go down to the gates.
