Chasidut su Genesi 29:27

Jacob spent seven years working for Rachel, and then Laban had him marry Leah. Once he found out that he had been tricked he waited seven days and then married Rachel in return for promising to work for another seven years (see Gen. 29:27-28). These two sets of seven, first years and then days, represent the full complement of seven. Jacob spiritually accomplished what seven times seven regular years usually accomplish. After the two sevens of forty-nine years, we have Yovel, and after Jacob’s two sevens he too received Yovel, the light of Messiah, through marriage with Rachel.
