So shall. — This clause is also in the optative: “let the communities of peoples be gathered round thee.”
For their sakes. — Rather, over or above it, as in LXX. The poet has a vision of judgment. Jehovah summons the nations, arranges them at His tribunal, and then returns to His high throne to preside. This explanation is more consonant with the context (see next verse) than to suppose the judgment to have taken place between the two causes of the verse, and the departure of God into the height “as a victor after battle” (Delitzsch), or “in proof of His supremacy as judge” (Ewald). This picture of arraigned nations is certainly in favour of the view which makes the psalm the expression of the feelings of the community rather than of an individual.
