κακοποιός [page 317]
An interesting instance of this Petrine adj. is afforded by PSI I. 64 .21 (i/B.C.?), where a woman promises her husband (?) μηδὲ ποι [ή ]σειν εἴς σε φάρμακα φίλτρα μηδὲ κακοποιὰ μήτε ἐν ποτοῖς μήτε ἐν βρωτοῖς : cf. especially 1Pe_4:15 where the word probably means a sorcerer, magician, or poisoner (Souter Lex. s.v. ). See also P Leid W xxiv. 18 (ii/iii A.D.) ἐπιμαρτυροῦντος μηδενὸς κακοποιοῦ Κρόνου , ἢ Ἄρεως .
