Genesis 29:1

1Then Jacob went on his journey, and came into the land of the people of the east.

2And he looked, and behold a well in the field, and, lo, there were three flocks of sheep lying by it; for out of that well they watered the flocks: and a great stone was upon the well’s mouth.

3And thither were all the flocks gathered: and they rolled the stone from the well’s mouth, and watered the sheep, and put the stone again upon the well’s mouth in his place.
