Moulton & Milligan — Vocabulary of the Greek NT
κατάθεμα is confined in Biblical Greek to Rev 223, but cf. the difficult Didache xvi. 5 οἱ δὲ ὑπομείναντες ἐν tr πίστει αὐτῶν It is apparently a stronger form of ἀνάθεμα (cf. Zech 144 and for the form SH on Rom 98), and in Rev Z.c. refers to the object on which a ban is laid, ‘an accursed thing.”” No instance of the word has yet been cited from profane writings, but see what is stated s.v. ἀνάθεμα.
