JST, Mark 9:40–48. Compare Mark 9:43–48
Jesus compares cutting off an offending hand or foot to discontinuing associations that may lead one astray.
40 Therefore, if thy hand offend thee, cut it off; or if thy brother offend thee and confess not and forsake not, he shall be cut off. It is better for thee to enter into life maimed, than having two hands, to go into hell.
41 For it is better for thee to enter into life without thy brother, than for thee and thy brother to be cast into hell; into the fire that never shall be quenched, where their worm dieth not, and the fire is not quenched.
42 And again, if thy foot offend thee, cut it off; for he that is thy standard, by whom thou walkest, if he become a transgressor, he shall be cut off.
43 It is better for thee, to enter halt into life, than having two feet to be cast into hell; into the fire that never shall be quenched.
44 Therefore, let every man stand or fall, by himself, and not for another; or not trusting another.
45 Seek unto my Father, and it shall be done in that very moment what ye shall ask, if ye ask in faith, believing that ye shall receive.
46 And if thine eye which seeth for thee, him that is appointed to watch over thee to show thee light, become a transgressor and offend thee, pluck him out.
47 It is better for thee to enter into the kingdom of God, with one eye, than having two eyes to be cast into hell fire.
48 For it is better that thyself should be saved, than to be cast into hell with thy brother, where their worm dieth not, and where the fire is not quenched.
