Ps 98:1-9. In view of the wonders of grace and righteousness displayed in God's salvation, the whole creation is invited to unite in praise.
1. gotten ... victory -- literally, |made salvation,| enabled Him to save His people.
right hand, and ... arm -- denote power.
holy arm -- or, |arm of holiness,| the power of His united moral perfections (Ps 22:3; 32:11).
2. salvation -- the result of His righteousness (Ps 7:17; 31:1), and both are publicly displayed.
3. The union of mercy and truth (Ps 57:3; 85:10) secure the blessings of the promise (Ge 12:3; 18:18) to all the world (Isa 52:10).
4-6. make a loud noise -- or, |burst forth| (Isa 14:7; 44:23).
before ... King -- hail Him as your sovereign; and while, with every aid to demonstrate zeal and joy, intelligent creatures are invited to praise, as in Ps 96:11-13, inanimate nature is also summoned to honor Him who triumphs and rules in righteousness and equity.
