Same or similar entry in other lexica (see the references at Photius theta17 Theodoridis), and cf. also scholia to two passages where the headword qami/zeis occurs: Homer, Iliad 18.386 (repeated 18.425), where its sense is 'you come often'; and Plato, Republic 328C.
This verb and the two verbs given in the gloss -- for which see again pi 3150 and, in reverse sigma 1698 -- may mean either "do (something) frequently" or perhaps "be frequently."
