Psalm 119:172

For we know that the Law is spiritual; but I am unspiritual, a slave sold to sin.

How can ye, evil as ye are, speak good things? For out of the abundance of the heart the mouth speaketh.

So that the Law is holy, and the commandment holy, and right, and good.

Let no foul language proceed out of your mouth, but whatever is good for edification, as the need may be, that it may benefit the hearers;

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

My tongue shall speak of thy word: for all thy commandments are righteousness.

How can ye, evil as ye are, speak good things? For out of the abundance of the heart the mouth speaketh.

Let no foul language proceed out of your mouth, but whatever is good for edification, as the need may be, that it may benefit the hearers;

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

So that the Law is holy, and the commandment holy, and right, and good.
