Psalms 150:1

God El, the God of sovereign power (Psalms 90:2).

in his sanctuary This may mean the temple (cp. Psalms 63:2, &c.), and the verse will then be a call to men to praise Jehovah in His earthly abode, and to angels to praise Him in heaven above. Cp. Psalms 148. But it is better to understand it to mean heaven (cp. Psalms 11:4). The whole verse will then be a Sursum Corda. Praise the holy God who dwells in His holy heaven (Psalms 20:6), the firmament which is His handiwork and the witness to His omnipotence. This, and not in his strongor indestructible firmament(ἐν τῷ στερεώματι τῷ ἀκαθαιρέτῳ αὐτοῦ Symm.), seems to be the meaning of the firmament of his power. The P.B.V. in his holinessis in itself possible, but contrary to the parallelism.
