John 14:5
“Lord, we know not whither You go.”
“The place,” he says, “we know not, and how shall we know the way leading there?” And observe with what submissiveness he speaks; he says not, “tell us the place,” but, “we know not whither You go”; for all had long yearned to hear this. If the Jews questioned among themselves when they heard (of His departure), although desirous to be rid of Him, much more would those desire to learn, who wished never to be separated from Him. They feared therefore to ask Him, but yet they asked Him, from their great love and anxiety. What then says Christ?
