Well, as an army chaplain I once felt led to share a sermon on cussing, which I analyzed into three main categories: the S-words, F-words and GD-words, which would be condemned by that commandment reaffirmed by Paul in:
TOP #164: Christians should not speak coarsely or unlovingly, but rather helpfully. [EPH 4:29 & 5:4] James states this teaching in terms of moral filth and controlling one’s tongue (JM 1:21 & 3:8-10).
I confess to not obeying this command sometimes, (usually when alone and an infernal inanimate object attacks me :^)
