= Synagoge epsilon704; Photius, Lexicon epsilon1626.
Both headword and gloss are present participles (the former middle, the latter active) in the masculine or neuter genitive singular.
Of the three extant attestations of the headword form outside lexicography, only Philo Judaeus (Quaestiones in Genesim 2 fr.13a) uses the word in a sense appropriate for the gloss here.
