Another glaring mistake is Mathew 25:46 which all Translations render: ““Then they will go away to eternal punishment, but the righteous to eternal life.” (https://biblehub.com/matthew/25-46.htm)
Only NW Translation puts their own thought into it and distorts the whole meaning: “These will depart into everlasting cutting-off.” (https://www.jw.org/en/library/bible/study-bible/books/matthew/25/)
The Greek word used is kolasis. “The word was originally a gardening word, and its original meaning was pruning trees. In Greek there are two words for punishment, timoria and kolasis, and there is a quite definite distinction between them. Aristotle defines the difference; kolasis is for the sake of the one who suffers it; timoria is for the sake of the one who inflicts it. Plato says that no one punishes (kolazei) simply because he has done wrong - that would be to take unreasonable vengeance (timoreitai). We punish (kolazei) a wrong-doer in order that he may not do wrong again (Protagoras 323 E). Clement of Alexandria (Stromateis 4.24; 7.16) defines kolasis as pure discipline, and timoria as the return of evil for evil. Aulus Gellius says that kolasis is given that a man may be corrected; timoria is given that dignity and authority may be vindicated (The Attic Nights7.14). The difference is quite clear in Greek and it is always observed. Timoria is retributive punishment. Kolasis is always given to amend and to cure. (From The Apostles’ Creed by William Barclay.)

Jesus is the one who used the word kolasis in Mathew 25:46. He never meant eternal cutting off because he had already made it clear what would happen to the unrighteous: “When Jesus heard this, he was amazed and said to those following him, “Truly I tell you, I have not found anyone in Israel with such great faith. I say to you that many will come from the east and the west, and will take their places at the feast with Abraham, Isaac and Jacob in the kingdom of heaven. But the subjects of the kingdom will be thrown outside, into the darkness, where there will be weeping and gnashing of teeth.” (Mathew 8:10-13) Also compare Mathew 19:28-30 which speaks of two contrasting groups of people---one group receives "100 times as much" whereas others receive something less about which they "will be weeping and gnashing of teeth.” To do this means they exist, not were cut off.
