The Lord is my shepherd

Psalm 23:1-6 (NKJV)

1 The Lord is my shepherd;
I shall not want.
2 He makes me to lie down in green pastures;
He leads me beside the still waters.
3 He restores my soul;
He leads me in the paths of righteousness
For His name’s sake.

4 Yea, 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.

5 You prepare a table before me in the presence of my enemies;
You anoint my head with oil;
My cup runs over.
6 Surely goodness and mercy shall follow me
All the days of my life;
And I will dwell in the house of the Lord
Forever.
