Vocabulary of the Greek NT

BGU IV. 1141.32 (B.C. 14) οὐδὲ γὰρ καθεύδωι ἔσωι ἵνα εἰδῶι, PSI I. 94.17 (ii/A.D.) καθεύδει τῇ νυκτί. In the rules regulating visitors to a sacred shrine, Syll 589.44 (iv/ B.C.), it is provided—ἐν δὲ τοῖ κοιμητηρίοι καθεύδειν χωρὶς μὲν τὸς ἄνδρας, χωρὶς δὲ τὰς γυναῖκας. The compound ἐγκαθεύδω occurs several times in the same document. We may add Epict. ii. 20. 10 βαλὼν κάθευδε καὶ τὰ τοῦ σκώληκος ποίει, ";lie down and sleep and play the part of the worm."; On the irregular construction in Mark 4:27 see Proleg. p. 185 f.
