Note: as we learn more about structure it becomes clear that chiastic inversion must also be seen in the wider context of the units of meaning indicated by other features of the text. The following is a lay out of the Psalm following the ESV versification but drawing attention to the inversion of five parts suggested by Dorsey.
A. 1 The LORD is my light and my salvation;
whom shall I fear?
the LORD is the strength of my life;
of whom shall I be afraid?
2 When the wicked, , came upon me
to eat up my flesh,
[even mine enemies and my foes]
they stumbled and fell.
3 Though an host should encamp against me,
my heart shall not fear:
though war should rise against me,
in this will I be confident.
4 One thing have I desired of the LORD,
that will I seek after;
that I may dwell in the house of the LORD
all the days of my life,
to behold the beauty of the LORD,
and to enquire in his temple.
5 Forhe shall hide me in his pavilion:
[in the time of trouble]
in the secret of his tabernacle shall he hide me;
he shall set me up upon a rock.
6 And now shall mine head be lifted up
above mine enemies round about me:
therefore will I offer in his tabernacle
sacrifices of joy;
I will sing, yea, I will sing praises unto the LORD.
C. 7 Hear, O LORD, when I cry with my voice:
have mercy also upon me, and answer me.
B’. 8 When thou saidst, Seek ye my face;
my heart said unto thee, Thy face, LORD, will I seek.
9 Hide not thy face far from me;
put not thy servant away in anger:
thou hast been my help;
leave me not,
neither forsake me,
O God of my salvation.
10 When my father and my mother forsake me,
then the LORD will take me up.
11 Teach me thy way, O LORD,
and lead me in a plain path,
because of mine enemies.
12 Deliver me not over unto the will of mine enemies:
for false witnesses are risen up against me,
and such as breathe out cruelty.
13 I had fainted, unless I had believed to see the goodness of the LORD in the land of the living.
14 Wait on the LORD:
be of good courage,
and he shall strengthen thine heart:
wait, I say, on the LORD.
