36 GreGOrY T.K. WOnG sections, there appears to be no recurrence of a key term that directly links the sections together. But in spite of the lack of recurring terms, the sections do share certain commonalities that link them together. Concerning the overall arrangement of the four sections into two halves on each side of the turning point, it has already been pointed out that vv. 4-12 and vv. 13-15, which precede the turning point, are characterised respectively by the exclusive use of third and first person subject references and verbs. The same dominance of third and first person subject references and verbs are also found respectively in vv. 18-20 and vv. 21-26, except that in these sections second person sub- ject references and verbs referring to God are also present. What this suggests is that prior to the turning point, the reality perceived is fo- cused exclusively on the wicked and the psalmist himself, with God not being part of the picture. But after the turning point, God, ad- dressed directly in the second person, enters the picture, and with that comes a vastly different perception of reality from before: characters who occupy favourable and unfavourable positions are suddenly re- versed. Thus, while in the yk section of vv. 4-12 the wicked seem to occupy a favourable position by their prosperity, in the yk section of vv. 21-26 it is now the psalmist who is blessed with the abiding pres- ence and fellowship of God. Likewise, while in the $a section of vv. 13-15 the psalmist seems to have occupied an unfavourable position by virtue of his daily afflictions, in the $a section of vv. 18-20 that un- favourable position has now gone to the wicked, who face imminent destruction from God. In this respect, even though no recurring term exists to directly link vv. 13-15 to vv. 18-20, by virtue of their con- trastive relationship with each other, which mirrors the contrastive relationship between the yk sections of vv. 4-12 and vv. 21-26, one can argue that the $a sections of vv. 13-15 and vv. 18-20 are also set against each other as corresponding parallel sections. 4. Additional Development of the Basic Ring All that has been demonstrated so far about the interrelationships that link the beginning, end, middle turning point, and the four corre- sponding parallel sections arranged chiastically on either side of the turning point would have been enough to support the claim that Psalm 73 is indeed a ring. But taking the circular nature of the ring one step further, the psalmist appears to have introduced an additional horizon- tal axis to turn the two sets of chiastically arranged sections on either side of the turning point into a true quadrant of four mutually corre- sponding sections.
