Adam Clarke on Psalms 47:5

God is gone up with a shout - Primarily, this may refer to the rejoicing and sounding of trumpets, when the ark was lifted up to be carried on the shoulders of the Levites. But it is generally understood as a prophetic declaration of the ascension of our Lord Jesus Christ; and the shout may refer to the exultation of the evangelists and apostles in preaching Christ crucified, buried, risen from the dead, and ascended to heaven, ever to appear in the presence of God for us. This was the triumph of the apostles; and the conversion of multitudes of souls by this preaching was the triumph of the cross of Christ.
