Photius, Lexicon kappa545 Theodoridis, has the same gloss for (?)kekwfeu=sqai. (Theodoridis notes the variant kekwfei=sqai, together with the Suda's kekwfh=sqai and Lobeck's conjecture kekwfw=sqai.)
The verb kwfa/w occurs five times in the passive in Philo Judaeus, including kekwfh=sqai in De congressu eruditionis gratia 65.7 (in a figurative sense) and kekwfw=sqai in Quod deterius potiori insidiari soleat 175.
