'Talk' in the Bible

Do not let unwholesome [foul, profane, worthless, vulgar] words ever come out of your mouth, but only such speech as is good for building up others, according to the need and the occasion, so that it will be a blessing to those who hear [you speak].

Let there be no filthiness and silly talk, or coarse [obscene or vulgar] joking, because such things are not appropriate [for believers]; but instead speak of your thankfulness [to God].
