Ephesians 5:13
Nestle 1904 Greek New Testament · Berean Standard Bible
τὰ δὲ πάντα ἐλεγχόμενα ὑπὸ τοῦ φωτὸς φανεροῦται πᾶν γὰρ τὸ φανερούμενον φῶς ἐστιν
But everything exposed by the light becomes visible (note: SBL begins verse 14 after visible,), for everything that is illuminated becomes a light itself.
