פירוש על בראשית 29:10

ויגש יעקב ויגל JACOB STEPPED NEAR AND ROLLED [THE STONE]- as easily as one draws the stopper from the mouth of a bottle — thus showing you how strong he was. (Bereishit Rabbah 70:12)

ויגל את האבן, seeing he was a son of her father’s sister.

כאשר ראה יעקב את רחל, until he had met Rachel Yaakov had not been interested to get involved in the problem of rolling the rock off the top of the well. He had been afraid that if he helped the three shepherds would only be concerned with watering their own flocks without waiting around to assist any other shepherds.
