Parallel
Matthew 6:22
Robinson-Pierpont Byzantine Textform · Berean Standard Bible
Ὁ λύχνος τοῦ σώματός ἐστιν ὁ ὀφθαλμός· ἐὰν οὖν ὁ ὀφθαλμός σου ἁπλοῦς ᾖ, ὅλον τὸ σῶμά σου φωτεινὸν ἔσται·
The eye is the lamp of the body. If your eyes are good (note: Literally If your eye is sound; see Proverbs 22:9), your whole body will be full of light.
