Genesis 29:1-3

1Jacob resumed his journey and came to the land of the people of the east. 2He looked and saw a well in the field, and near it lay three flocks of sheep, because the sheep were watered from this well. And a large stone covered the mouth of the well. 3When all the flocks had been gathered there, the shepherds would roll away the stone from the mouth of the well and water the sheep. Then they would return the stone to its place over the mouth of the well.
