Luke 20:3

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

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

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

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