psychology poetry and me

The Lord is my shepherd, I lack nothing
he refreshes my soul.
He guides me along the right paths
for his name's sake.Even though I walk
through the darkest valley,I will fear no evil,
for you are with me;
your rod and your staff,
they comfort me.You prepare a table before me
in the presence of my enemies.
You anoint my head with oil;
my cup overflows.
Surely your goodness and love will follow me
all the days of my life,
and I will dwell in the house of the Lord
forever.
