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.
Textus Receptus (TR) - 1 Corinthians 5:1 >Ὅλως ἀκούεται ἐν ὑμῖν πορνεία, καὶ τοιαύτη πορνεία, ἥτις οὐδὲ ἐν τοῖς ἔθνεσιν ὀνομάζεται, ὥστε γυναῖκά τινα τοῦ πατρὸς ἔχειν.
