Matthew Poole and continuators on Psalms 50:2

2. Out of Zion the perfection of beauty , God hath shined e.

The place where he was supposed to reside, and where he would now sit in Judgment. Or, from whence he would come to a more publick and Conspicuous place, where all the World might see and hear the Transactions.

The most beautiful and amiable place of the whole World, because of the Presence and Worship, and Blessing of God, which was there and there onely (i. e.) Hath appeared, or manifested himself in a glorious manner, as Judges do when they come to the Judgment seat.
