Moulton & Milligan — Vocabulary of the Greek NT
ἀνακόπτω. P Flor I. 36% (early iv/A.D.) crimes ὑφ᾽ οὐδενὸς ἄλλου ἀνακόπτεται, but by the punishment of the criminal; a similar connotation probably may be recognised in the fragmentary P Giss I. 872° (ii/A.p.) . .] παραγγέλλειν ἀνακοπῆναι [- . , from what the scanty context suggests. So also in P Théad 19!8 (iv/A.D.) δέομαι τῆς σῆς ἀρε[ TH]s κελεῦσαι. . . τὴν παιδιὰν τῆς γυναικὸς ἀνακοπῆναι δι’ οὗ εὐδοκιμάσῃς. The word obviously does not encourage us to approve the few cursives that show it in Gal 5’.
