John Mark
Mark 9:46KJV·traditional attribution
Where their worm dieth not, and the fire is not quenched.
Matthew Henry Presbyterian
Here, I. Christ promiseth a reward to all those that are any way kind to his disciples (Mar 9:41); "Whosoever shall give you a cup of water, when you need it, and will be a refreshment to you, because ye belong to Christ, and are of his family, he shall not lose his reward." Note, 1.
Commenting on Mark 9:41-50
John Gill Reformed Baptist
Where their worm dieth not, and the fire is not quenched. This is repeated again, not only to assure the truth of the thing, but to raise the attention of the mind unto it, and fix an awful impression upon it: the Persic version renders it, "from whence thou shall never find redemption": there is no redemption from hell, as Origen and others have thought.
