O clap your hands, all ye people - A common way of expressing joy, or indicating applause. Compare the notes at Isaiah 55:12. The “people” here referred to are probably the Jewish people, and the call on them is to rejoice, with the customary marks of joy, in view of the great victory which God had gained over their enemies.
Shout unto God - Make a joyful noise in praise of God; that is, in acknowledgment that this victory has been gained by his interposition.
With a voice of triumph - With such a shout as is usually raised when a victory is obtained; such a shout as occurs in a triumphal procession. Compare 2 Samuel 6:15; 1 Chronicles 15:28; Job 39:25; Zechariah 4:7; Exodus 32:18; Isaiah 12:6; Isaiah 42:11; Isaiah 44:23; Jeremiah 50:15. There are doubtless times when loud shouts, as expressive of joy, are proper.
