I don't think that the Bible was necessarily concerned about specific words, some that did not exist at that time, but harmful words in general:
18“But the things that proceed out of the mouth come from the heart, and those defile the man.
19“For out of the heart come evil thoughts, murders, adulteries, fornications, thefts, false witness, slanders.
20“These are the things which defile the man; but to eat with unwashed hands does not defile the man.”
Ephesians 4:29New American Standard Bible (NASB)
29 Let no unwholesome word proceed from your mouth, but only such
a word as is good for edification according to the need
of the moment, so that it will give grace to those who hear.
As much Bible study as I have done, though most is in the field of eschatology and manuscripts (textual criticism), I like many people struggle at times, and probably do not get as ruffled at times like I do on this site. I am working to get better at it, but there are a few downright evil and insulting people on this site, some that it is in their sole existence to be vile and push people to get to their level of existence. May they are mostly a bunch of immature kids or young teenagers, I don't know, but they try at every moment or level to throw gasoline on a fire, trying to invoke a reaction to get their jollies. I hope to continue to get stronger to resist these certain people, though that doesn't keep them from continuing to try.
I am likely to revisit the studies and book outline I was constructing of the Book of Revelation. I have much unfinished work here, and need to refresh what I researched in the past. So it is in the field of eschatology that I will say that I am the most adept.
