Let no corrupt communication proceed out of your mouth, but [only] that which is good . . . [and] edifying, that it may minister grace unto the hearers.
And grieve not the holy Spirit of God. . . .
Let all bitterness, and wrath, and anger, and clamour, and evil speaking, be put away from you. . . .
And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ's sake hath forgiven you.
