גָּ֘ד֤וֹל יְהוָ֣ה וּמְהֻלָּ֣ל מְאֹ֑ד בְּעִ֥יר אֱ֝לֹהֵ֗ינוּ הַר־קָדְשֽׁוֹ׃
여호와는 광대하시니 우리 하나님의 성, 거룩한 산에서 극진히 찬송하리로다
Rashi on Psalms
in the city of our God In the future, when He builds His city, He will be great and praised because of it.
Metzudat David on Psalms
In the city of our God – that is to say that when He causes His Presence to rest in Jerusalem, His holy mountain. Then He will be great and very much praised in the mouths of all.
