Psalms 29:2 - Matthew Poole's English Annotations on the Holy Bible

The glory due unto his name, i.e. the honour which he deserves; which is to prefer him before all other gods, and to forsake all others, and to own him as the Almighty, and the only true God. In the beauty of holiness; or, of the sanctuary, which is commonly called by this name; in his holy and beautiful house, as it is called, Isaiah 64:11, the only place where he will receive worship. So he exhorts them to turn proselytes to the Jewish religion; which was their duty and interest.
