창세기 41:53 해설: Chizkuni, Da'at Zekenim & Radak

ותכילנה, “they came to an end;” this unusual expression for describing the end of something is based on כלולות יופי, “they were completely beautiful, because fully sated.”

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.

אשר היה, a collective term, hence in the singular היה instead of the plural היו.
