Thematic Bible: Often covered to prevent their being filled with sand

He looked, and saw a well in the field, and behold, three flocks of sheep were lying there beside it, for from that well they watered the flocks. Now the stone on the mouth of the well was large. When all the flocks were gathered there, they would then roll the stone from the mouth of the well and water the sheep, and put the stone back in its place on the mouth of the well.
