'Unquenchable' in the Bible

His winnowing fork is in his hand, and he will thoroughly cleanse his threshing floor. He will gather his wheat into the barn, but the chaff he will burn up with unquenchable fire."

If your hand causes you to stumble, cut it off. It is better for you to enter into life maimed, rather than having your two hands to go into Gehenna, into the unquenchable fire,

whose fan is in his hand, and he will thoroughly cleanse his threshing floor, and will gather the wheat into his barn; but he will burn up the chaff with unquenchable fire."
