what is knows as the shepherd,s psam'? IN the bible?

Answer 1

The 23rd Psalm (the one they tend to read at funerals for some strange reason). The Lord is my shepherd; I shall not want.
He maketh me to lie down in green pastures: he leadeth me beside the still waters. He restoreth my soul: he leadeth me in the paths of righteousness for his name's sake.Yea, though I walk through the valley of the shadow of death, I will fear no evil: for thou art with me; thy rod and thy staff they comfort me.
Thou preparest a table before me in the presence of mine enemies: thou anointest my head with oil; my cup runneth over.
Surely goodness and mercy shall follow me all the days of my life: and I will dwell in the house of the Lord forever.

Answer 2

I think you're thinking of Psalm 23

1 The LORD is my shepherd, I shall not be in want.
2 He makes me lie down in green pastures,
he leads me beside quiet waters,

3 he restores my soul.
He guides me in paths of righteousness
for his name's sake.

4 Even though I walk
through the valley of the shadow of death, [a]
I will fear no evil,
for you are with me;
your rod and your staff,
they comfort me.

5 You prepare a table before me
in the presence of my enemies.
You anoint my head with oil;
my cup overflows.

6 Surely goodness and love will follow me
all the days of my life,
and I will dwell in the house of the LORD
forever.

It is often said at funerals, I believe.
