Taketh away vs Purgeth in John 15:2

Here are some more information that you can chew on.

Purgeth. Gr. kathairo, "to cleanse," in this case, by removing superflous growth. There is a word play in the Greek in the words for "taketh away" (airo) and "purgeth" (kathairo) that cannot be reproduced in English. The character is "purged" by the test and trials of life. The Father, the heavenly Husbandman, oversees the process. And though the "chastening" may seem to be grievous, "nevertheless afterward it yieldeth the peaceable fruit of righteousness unto them which are exercised thereby" Heb. 12:11) - from 5 BC p. 1024
