I walk through the valley of the shadow of death.
And I fear no evil because I’m blind to it all.
In my mind, my gun they comfort me,
because I know I’ll kill my enemies when they come.
Surely goodness and mercy will follow me all the days of my life,
and I will dwell on this earth forevermore.
So I walk beside the still waters and they restore my soul,
but I can’t walk on the path of the right because I’m wrong.
No I can’t walk on the path of the right because I’m wrong.
