from Kenneth Bailey: The Good Shepherd, SPCK.

A. 1 The LORD is my shepherd;
I shall not want.

B. Food and drink

2 He maketh me to lie down
in green pastures:
he leadeth me beside the still waters.

C. security

3 He restoreth my soul:
he leadeth me in the paths of righteousness
for his name’s sake.

D. 4 Yea, though I walk through the valley
of the shadow of death,
I will fear no evil:

C’. security

for thou art with me; 
thy rod and thy staff
they comfort me.

B’. Food and drink

5 Thou preparest a table before me
 in the presence of mine enemies:
thou anointest my head with oil;
my cup runneth over.

A’. 6 Surely goodness and mercy
shall follow me all the days of my life:
and I will dwell in the house of the LORD
for ever.
