As soon as Jacob saw Rachel, the daughter of his mother’s brother Laban, with Laban’s sheep, he went up and rolled the stone away from the mouth of the well and watered his uncle’s sheep.
Here we see, 1. Rachel's humility and industry: She kept her father's sheep (Gen 29:9), that is, she took the care of them, having servants under her that were employed about them. Rachel's name signifies a sheep. Note, Honest useful labour is that which nobody needs be ashamed of, nor ought it to be a hindrance to any one's preferment. 2. Jacob's tenderness and affection.
Commenting on Genesis 29:9-14
And it came to pass, when Jacob saw Rachel, the daughter of Laban his mother's brother,....

Jacob went near, and rolled the stone - Probably the flock of Laban was the last of those which had a right to the well; that flock being now come, Jacob assisted the shepherds to roll off the stone, (for it is not likely he did it by himself), and so assisted his cousin, to whom he was as yet unknown, to water her flock.
