Psalm 92/Notes/Grammar.V. 14.307020
From Psalms: Layer by Layer
The preferred two separate clauses are found in the ESV, DHH, RVC. See the symmetry of the two locative prepositional phrases, which indicate the status of שְׁ֭תוּלִים בְּבֵ֣ית יְהוָ֑ה as an independent clause. For a similar, future referring verbless clause with both subject and copula elided, see Ps 1:4b.
For a similar shift from singular צָדִּיק to collective reference, see Job 36:7 – לֹֽא־יִגְרַ֥ע מִצַּדִּ֗יק עֵ֫ינָ֥יו וְאֶת־מְלָכִ֥ים לַכִּסֵּ֑א וַיֹּשִׁיבֵ֥ם לָ֝נֶ֗צַח וַיִּגְבָּֽהוּ (cf. Ps 78:1-4). Alternatively, for lack of a subject, TgPs provides בנוי ("his sons").
