7. ἐν τῇ διδασκαλία ἀφθορίαν. This is undoubtedly the true reading and is found in א*ACD2*E*KLP; G has ἀφθονίαν. The rec. text has ἀδιαφθορίαν with אcD2cE**L and cursives.
After σεμνότητα the rec. text adds ἀφθαρσίαν, with D2cE**KL and about 30 cursives; instead of which C and a few other authorities have ἁγνείαν. But neither addition is sufficiently well supported to entitle it to a place in the text.
