Romans 2:14
Robinson-Pierpont Byzantine Textform · Berean Standard Bible
Ὅταν γὰρ ἔθνη τὰ μὴ νόμον ἔχοντα φύσει τὰ τοῦ νόμου ποιῇ, οὗτοι, νόμον μὴ ἔχοντες, ἑαυτοῖς εἰσιν νόμος·
Indeed, when Gentiles, who do not have the law, do by nature what the law requires, they are a law to themselves, even though they do not have the law.
