Charles H. Spurgeon on Psalms 29:9

In his temple. Some conceive that this Psalm was appointed by David to be sung in the temple in time of thunder, which is not unlikely. There are writers who make God to be the nominative case to the verb speaketh; and render it thus, in his temple doth he utter all his glory. As much as to say, much of his glory God uttereth in his thunder, but all in his temple, for whatsoever there he speaketh with his mouth he fulfils it with his hand. John Trapp.
