The wider sense of evil-doing from a moral point of view, as in 1Pe_3:17 , 3Jn_1:11 , may be illustrated by P Hib I. 59 .10 ( c. B.C. 245) εἰ μὴ παύσει κ̣[α ]κοποῶν ἐν τῆι κώμη [ι ] μεταμελή [σ ]ει σοι , if you do not stop your malpractices in the village you will repent it (Edd.), P Ryl II. 437 .7 (i/A.D.) ἐὰν κακοποιο [ ] καὶ ἄπρακτα τ̣[ ] εἰς πλοῖον ἐλ [ is too fragmentary to enable us to determine the exact force, but it seems to point to a more restricted sense injure, do harm to, as in the few occurrences of the verb in class. literature, and in Syll 653 .103 (B.C. 91) ἐχέτω δὲ ἐπιμέλειαν ὁ ἀγορανόμος καὶ περὶ τοῦ ὕδατος , ὅπως . . . . μηθεὶς κακοποιεῖ μήτε [τὸ ] πλῆμα μήτε τοὺς ὀχετούς , ib. 893 .15 (ii/A.D.) εἰ δέ τις τὴν ἐπιγραφὴν ἐκκόψῃ ἐκ τῆς παραστά [δο ]ς ἢ αὐτὴν ἄρῃ ἢ κακο [ποι ]ήσῃ , δώσ (ε )ι κτλ .
