Matthew 18:8

8 `And if thy hand or thy foot doth cause thee to stumble, cut them off and cast from thee; it is good for thee to enter into the life lame or maimed, rather than having two hands or two feet, to be cast to the fire the age-during.

Matthew 18:8 Meaning and Commentary

Ver. 8, 9. Wherefore if thy hand or thy foot
The same words are repeated here on occasion of offences, as are spoken by Christ, ( Matthew 5:29 Matthew 5:30 ) on account of unchaste looks, desires and lusts: giving offence to Christ's disciples, or endeavouring, by any means whatever, to cause them to stumble and fall, is equally gratifying the flesh, and no more to be indulged, than the other, on pain of eternal damnation. (See Gill on Matthew 5:29) (See Gill on Matthew 5:30)
