Regarding swear or cuss words, there’s more cultural distinction than biblical instruction involved with the rules. Different languages have different kinds of taboo words for various reasons. So the Bible doesn’t explicitly state a specific word is taboo, nor are there any Hebrew or Greek translations of swear words in English. Unless we are cursing or insulting someone, using certain words is not a sin. Words are just words, whether it be in some generic colloquial expression of pain or angst (what the f*** or oh s***), or using a word in its proper context like referring to a donkey (ass), or female dog (bitch). A lot of our modern Western English swear words actually have legitimate context, so when using them in context, it’s not an issue.
