Matthew 5:29 in the King James Version
And if thy right eye offend thee, pluck it out, and cast it from thee: for it is profitable for thee that one of thy members should perish, and not that thy whole body should be cast into hell.
Context
28 but I tell you that everyone who gazes at a woman to lust after her has committed adultery with her already in his heart.
29 If your right eye causes you to stumble, pluck it out and throw it away from you. For it is more profitable for you that one of your members should perish than for your whole body to be cast into Gehenna.
30 If your right hand causes you to stumble, cut it off, and throw it away from you. For it is more profitable for you that one of your members should perish, than for your whole body to be cast into Gehenna.
