CHRISTIAN: "No, if you please, let me go ahead — so that if there is any
danger, I may meet it first — because by my guidance we have both gone
out of the way.”
HOPEFUL: "No — you shall not go first; for your mind is troubled,
and you may lead us out of the way again."

your heart toward the highway — even the way by which you came;
turn back."
But by this time the waters had greatly risen — so the way of going back
was very dangerous. Then Christian realized that it is easier to go out of
the right way — than to get back into it.
So they attempted to go back — but it was so dark, and the flood was so
high, that they almost drowned nine or ten times. Neither could they,
using all their skill — get back to the stile that night. At last, finding a
little shelter — they sat down there. Being weary, they fell asleep until
the day-break.
Jeremiah 31:21

even the way by which you went: turn again,
