Luke 20:3

Then he answering said to them, I also will ask you one question; and resolve me:

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

and if I shall ask you any question, ye will neither answer me, nor let me go free.

Let your discourse be always gracious, seasoned with salt, that ye may know how ye ought to reply to every man.
