1 Corinthians 5:1

1 It is reported commonly that there is fornication among you, and such fornication as is not so much as named among the Gentiles, that one should have his father's wife.
Ὅλως ἀκούεται ἐν ὑμῖν πορνεία καὶ τοιαύτη πορνεία ἥτις οὐδὲ ἐν τοῖς ἔθνεσιν ὀνομάζεται, ὥστε γυναῖκά τινα τοῦ πατρὸς ἔχειν
