C. F. Keil and Franz Delitzsch on Psalms 97:1

The Breaking Through of the Kingdom of God, the Judge and Saviour

This Psalm, too, has the coming of Jahve, who enters upon His kingdom through judgment, as its theme, and the watchword “Jahve is King” as its key-note. The lxx inscribes it: τῷ Δαυίδ ὅτε ἡ γῆ αὐτοῦ καθίσταται (καθίστατο); Jerome: quando terra ejus restituta est. The τῷ Δαυίδ is worthless; the time of restoration, from which it takes its rise, is the post-exilic, for it is composed, as mosaic-work, out of the earlier original passages of Davidic and Asaphic Psalms and of the prophets, more especially of Isaiah, and is entirely an expression of the religious consciousness which resulted from the Exile.
