'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 sound of those who divide their work loads at the watering troughs, there they will retell the righteous deeds of the LORD, the righteous victories for his rural people in Israel." Then the people of the LORD went down to the gates.
