A Levite Blows the Shofar as the People Clapby emmanuel_higgins

Psalms 47:1

O clap your hands, all ye people; shout unto God with the voice of triumph.

The call goes out to all peoples without exception to break into loud, open exultation and triumph in God. That triumph is not to remain inward or silent but to find voice in audible praise uttered together in the assembled congregation. Such resounding praise is the fitting answer to His greatness and mighty power. Though His holiness strikes the transgressor with terror, He regards the guilty with compassion and yearns for them to turn to Him and be saved.
