משך חכמה — וישב לבן למקומו ויעקב הלך לדרכו

Q — What is the significance of the precise contrast — "לבן returned to his place" while "Yaakov went on his way"?

A — A rasha like Lavan, even after twenty years with a tzaddik in his home, returns to his original low state of deceit and greed ("למקומו"); a tzaddik like Yaakov never returns and never stands still — "תלמידי חכמים אין להם מנוחה" — they keep ascending, which is why the moment Yaakov leaves Lavan, מלאכי אלוקים immediately meet him.
