ותכלינה. על שם שהיו הבריות כלולות ביופי מתוך השבע: ותכילנה, “they came to an end;” according to B’reshit Rabbah, 90,6 the word is to be understood as derived from כלולות as in כלולותיך in Jeremiah 2,2, a reference to physical beauty, i.e. the seven years of plenty had resulted in the whole Egyptian population having a more pleasing and healthy appearance.
