A Song and Psalm for the sons of Korah. Great is the LORD, and greatly to be praised in the city of our God, in the mountain of his holiness. Great is the Lord - This verse should be joined to the last verse of the preceding Psalm, as it is a continuation of the same subject; and indeed in some of Kennicott's MSS. it is written as a part of the foregoing. That concluded with He is greatly exalted; this begins with Great is the Lord, and greatly to be praised; i.e., He should be praised according to his greatness; no common praise is suited to the nature and dignity of the Supreme God.
In the city of our God - That is, in the temple; or in Jerusalem, where the temple was situated.
The mountain of his holiness - Mount Moriah, on which the temple was built. The ancient city of Jerusalem, which David took from the Jebusites, was on the south of Mount Zion, on which the temple was built, though it might be said to be more properly on Mount Moriah, which is one of the hills of which Mount Zion is composed. The temple therefore was to the north of the city, as the psalmist here states, Psalms 48:2 : "Beautiful for situation, the joy of the whole earth, is Mount Zion, on the sides of the north, the city of the great King." But some think that it is the city that is said to be on the north, and Reland contends that the temple was on the south of the city.
