5:29 And if thy {r} right eye {s} 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.
(r) He names the right eye and the right hand, because the parts of the right side of our bodies are the chiefest, and the most ready to commit any wickedness.
(s) Literally, do cause you to offend: for sins are stumbling blocks as it were, that is to say, rocks which we are cast upon.
5:29 If thy right eye offend thee. The eye that giveth a lustful look. A licentious passion, or anything that tempts to sin, whether thoughts within, friends, or surroundings.
Pluck it out. Cast far from you what would lead to sin.
It is profitable. Better to suffer deep mortification by self-denial than to be judged worthy of hell.
Thy whole body. Used for the whole man.
5:29-30 If a person as dear as a right eye, or as useful as a right hand, cause thee thus to offend, though but in heart. Perhaps here may be an instance of a kind of transposition which is frequently found in the sacred writings: so that the 29th verse may refer to 27, 28; and the 30th to ver. 21, 22. Mt 5:29,27,28,30,21,22 As if he had said, Part with any thing, however dear to you, or otherwise useful, if you cannot avoid sin while you keep it. Even cut off your right hand, if you are of so passionate a temper, that you cannot otherwise be restrained from hurting your brother. Pull out your eyes, if you can no otherwise be restrained from lusting after women. Matt 18:8; Mark 9:43.
5:27-32 Victory over the desires of the heart, must be attended with painful exertions. But it must be done. Every thing is bestowed to save us from our sins, not in them. All our senses and powers must be kept from those things which lead to transgression. Those who lead others into temptation to sin, by dress or in other ways, or leave them in it, or expose them to it, make themselves guilty of their sin, and will be accountable for it. If painful operations are submitted to, that our lives may be saved, what ought our minds to shrink from, when the salvation of our souls is concerned? There is tender mercy under all the Divine requirements, and the grace and consolations of the Spirit will enable us to attend to them.
