This book of the law
shall not depart out of your mouth,
but you shall meditate on it
         day and night,
that you may be careful to do
according to all
      that is written in it;
for then
   you shall make your way prosperous,
and then
   you shall have good success.
Have I not commanded you?
Be strong and of good courage;
     be not frightened,
     neither be dismayed,
for the LORD your God
is with you
         wherever you go.

                        Joshua 1. 8-9

(When my heart is filled
      with the Word of God,
there is no room for fear,
nor any reason for it.)
