Matthew 5:29

Eἰ δὲ ὁ ὀφθαλμός σου ὁ δεξιὸς σκανδαλίζει σε, ἔξελε αὐτὸν καὶ βάλε ἀπὸ σοῦ· συμφέρει γάρ σοι ἵνα ἀπόληται ἓν τῶν μελῶν σου καὶ μὴ ὅλον τὸ σῶμά σου βληθῇ εἰς Γέενναν.

And if your right eye cause you to stumble, pluck it out, and cast it from you; for it is better for you that one of your members perish, and not your whole body to be thrown into Gehenna.
