Nor should there be obscenity, foolish talk or coarse joking, which are out of place, but rather thanksgiving. (NIV)
Let there be no filthiness (obscenity, indecency) nor foolish and sinful (silly and corrupt) talk, nor coarse jesting, which are not fitting or becoming; but instead voice your thankfulness [to God]. (AMP)
Neither filthiness, nor foolish talking, nor jesting, which are not convenient: but rather giving of thanks. (KJV)
