Luke 20:3

And he answered and said unto them, I will also ask you one thing; and answer me:

Why do your disciples transgress the tradition of the elders? for they wash not their hands when they eat bread.

And if I also ask you, you will not answer me, nor let me go.

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