Ewald and others imagine that this Psalm is made up of two fragments of separate Psalms composed at different periods and brought together by a later editor!
But this is disproved not only by what has been said concerning the structure of the Psalm as a whole, and the interlacing of the astronomical and the literary terms in the two parts, but it is also shown by more minute details.
Each half consists of two portions which correspond the one to the other, A answering to A, and B to B. Moreover, each half, as well as each corresponding member, consists of the same number of lines; those in [pg 004] the first half being, by the cæsura, short, while those in the last half are long (or double).
A | 1-4-. Eight lines
B | -4-6. Six lines
A | 7-10. Eight lines
B | 11-14. Six lines
If we confine ourselves to the first half of the Psalm[3] (A and B, verses 1-6), with which we are now alone concerned, we see a still more minute proof of Divine order and perfection.
The Structure of A and B.
A & B | C | 1. The heavens.
