Psalms of DavidThe Psalms of David - There are 150 psalms in the Old Testament.  About half are attributed to King David.  David was described as a skillful musician and played for Saul to ease his torment (I Samuel 16:16-19).  Psalm 23 is perhaps the most famous, and is a psalm of David:

 

"The Lord is my shepherd,
I shall not want.
He makes me lie down in green pastures;
He leads me beside quiet waters.
He restores my soul;
He guides me in the paths of righteousness
For his name's sake.

Even though I walk through the valley of the shadow of death,
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 have anointed my head with oil;
My cup overflows.
Surely goodness and loving kindness will follow me all the days of my life,
And I will dwell in the house of the Lord forever."

 

In addition, he wrote a line in Psalm 22 which is interpreted by Christians as prophecy of how the messiah would die.

 

"A band of evildoers has encompassed me;
They pierced my hands and my feet." (Psalm 22:16, NASB)
