'Well's' in the Bible

As he looked, he saw a well in the field, and three flocks of sheep lying there [resting] beside it because the flocks were watered from that well. Now the stone on the mouth of the well [that covered and protected it] was large,

and when all the flocks were gathered there, the shepherds would roll the stone from the mouth of the well, water the sheep, and [afterward] replace the stone on the mouth of the well.

But they said, “We cannot [leave] until all the flocks are gathered together, and the shepherds roll the stone from the mouth of the well; then we will water the sheep.”

When Jacob saw [his cousin] Rachel, the daughter of Laban, his mother’s brother, and Laban’s sheep, he came up and rolled the stone away from the mouth of the well and watered the flock of Laban, his uncle.

And the woman [of the house] took a covering and spread it over the mouth of the well and scattered grain on it; so nothing was discovered.
