"As long as it is day, we
must do the work of him
who sent me. Night is
coming, when no one
can work.  While I am in
the world, I am the light
of the world."
Having said this, he spit
on the ground, made
some mud with the
saliva, and put it on the
man's eyes.   "Go," he
told him, "wash in the
Pool of Siloam" (this
word means Sent). So
the man went and
washed, and came
home seeing.
John 9:4-7
