     يؤخذ طرخشقون مجفف وعدس ونورة أجزاء سواء ويسحق الجميع وينخل ويعجن بسمن بقري عتيق ثم يوضع منه على فتيلة ويدخل في الناصور نافع وربما نفع وربما نفع منه الكي بالنار.

Etymology 4

Compare Hebrew כִ֗י (kī) in Job 39:27, occurring together with נֶשֶׁר (néšer, “eagle; vulture”) and there sometimes, albeit dubiously, given the meaning “vulture”. אִם־עַל־פִּ֭יךָ יַגְבִּ֣יהַּ נָ֑שֶׁר וְ֝כִ֗י יָרִ֥ים קִנֹּֽו: “Is it upon your behest that the eagle and the vulture soars and makes his nest high?” Otherwise it is the well-known emphasizing particle כִּי (kī): “Is it upon your behest that the eagle soars, and yea, makes his nest high?”.
