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?”.
