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

And he looked, and lo! a well, in the field and lo! there, three flocks of sheep, lying down near it, for out of that well, do they water the flocks, but, the stone, is great, on the mouth of the well: so they gather together thither all the flocks, and roll away the stone from off the mouth of the well, and water the sheep, - and put hack the stone upon the mouth of the well, to its place.
