Musar su Salmi 119:164

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.
