Analysis of The Twenty-Third Psalm

My Shepherd is the Lord my God,--
 There is no want I know;
His flock He leads in verdant meads,
 Where tranquil waters flow.

He doth restore my fainting soul
 With His divine caress,
And, when I stray, He points the way
 To paths of righteousness.

Yea, though I walk the vale of death,
 What evil shall I fear?
Thy staff and rod are mine, O God,
 And Thou, my Shepherd, near!

Mine enemies behold the feast
 Which my dear Lord hath spread;

And, lo! my cup He filleth up,
 With oil anoints my head!

Goodness and mercy shall be mine
 Unto my dying day;
Then will I bide at His dear side
 Forever and for aye!
