מָלַ֣ךְ אֱ֭לֹהִים עַל־גּוֹיִ֑ם אֱ֝לֹהִ֗ים יָשַׁ֤ב ׀ עַל־כִּסֵּ֬א קָדְשֽׁוֹ׃
God reigneth over the nations; God sitteth upon His holy throne.
Rashi on Psalms
God has sat upon His holy throne Now the throne is complete and the greatness is recognized, and they will declare that the volunteers of the people have gathered to His city.
