Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers.
All Commentaries on Ephesians 4:29 Go To Ephesians 4
Irenaeus of Lyons
AD 202
And, "Let no corrupt communication proceed out of your mouth, neither filthiness, nor foolish talking, nor scurrility, which are not convenient, but rather giving of thanks."
