Charles H. Spurgeon on Psalms 150:1

In his sanctuary. wvdqb. Many have been the notions of the commentators as to the shade of meaning here; for the word differs from the form in Ps 20:2 vdwqm (from the sanctuary). The Vulgate adopts the plural rendering, in sanctis ejus, "in his holy places." Campensis renders it, ob insignem sanctitatem ipsius, "because of his excellent holiness." Some see under the word an allusion to the holy tabernacle of Deity, the flesh of Christ. Luther, in his German version, translates thus: in seinem Heiligthum, "in his holiness." The same harmony of comparative thought appears in the two clauses of this verse as in such passages as 1Ki 8:13,49 Isa 62:15. The place of worship where God specially hears prayer and accepts praise, and the firmament where angels fly at his command, and veil their faces in adoration, are each a sanctuary. The sanctuary is manifestly here looked at as the temple of grace, the firmament as the temple of power. So the verse proclaims both grace and glory. —Martin Geier.
