Musar su Genesi 29:27

All the elements of time described above, played a part in the labours which the Torah describes Jacob as performing for Laban, and in the wedding feast described in our פרשה. The "days" we spoke of are the seven days of the wedding feast. Rashi already explained that when Laban asked Jacob: מלא שבוע זאת, "complete the week of this one" (Leah), he referred to the seven-day wedding feast. He bases himself on the half vowel Sheva instead of the full vowel kametz that we would have expected under the letter ש (Genesis 29,27). This is why the Jerusalem Talmud Moed Katan states that this instance is the origin of the custom to entertain the groom and bride for seven days starting with the wedding. You also find the time unit "month" mentioned here, when Jacob stayed with Laban for a month (29,14) before starting to be recompensed for any services performed. The time unit "year" is mentioned in the agreement that Jacob was to serve seven years for Rachel. This unit of seven years is the forerunner of the unit שמטה as a time unit or cycle of seven years (29,18). Just as the release from monies owed takes effect only at the end of the שמטה year, so Rachel was not promised to Jacob till the end of the seven years' service.

During the first seven years that Jacob served Laban, he was under the impression that he was serving for Rachel. In truth, his service was actually perceived as in the domain of the hidden, a domain analogous to the mystique of Leah. It was accounted for him as seven שמטות, units of seven years each. Even though these years in the emanation בינה are portrayed as 49 years (not as 7 שמטות) the Zohar explains that when Laban said to Jacob in Genesis 29,27: מלא שבוע זאת, the emphasis on that שבוע was an allusion to Psalms 119,164: שבע ביום הללתיך, "I have praised you seven times on the same day," that during the seven days that the wedding with Leah was being celebrated all the missing years were telescoped into days.
