Psalm 119:172

For we know that the law is spiritual: but I am carnal, sold under sin.

O race of vipers, how can ye speak good things, who are yourselves so wicked? for out of the abundance of the heart the mouth speaketh.

So that the law is holy; and the commandment holy, and just, and good.

Let no corrupt word come out of your mouth; but what is good to useful edification, that it may benefit the hearers.

Let your speech be always with grace, seasoned with discretion to know how ye ought to answer every one.
