Genesis 29:1-3

Then Jacob set out on his journey, and went to the land of the people of the east.

He looked, and saw a well in the field, and behold, three flocks of sheep were lying there beside it, because they watered the flocks from that well. Now the stone on the mouth of the well was large.

When all the flocks were gathered there, they would roll the stone from the mouth of the well and water the sheep. Then they would put the stone back in its place on the mouth of the well.
