Genesis 29:3

And thither were all the flocks gathered
The three above mentioned, ( Genesis 29:2 ) : and they rolled the stone from the well's mouth, and watered the
sheep;
that is, when they watered the sheep, they used to roll away the stone from the mouth of the well in order to do it; for as yet the flocks, now lying by it, had not been watered, as appears from ( Genesis 29:7 Genesis 29:8 ) : and put a stone upon the well's mouth in this place;
this they were wont to do every time they watered the flocks.
