For the general design and scope of this chapter, see the Analysis to Isaiah 24. It is a song of praise to God for the anticipated deliverance of his people from the bondage in Babylon. The desolation of Jerusalem and Judah had been described in Isaiah 24; that chapter had closed with an intimation that Yahweh would again reign in glory on Mount Zion Isaiah 24:23; and in view of this future deliverance the prophet breaks out into this beautiful song of praise. It was not unusual for the prophets to express, by anticipation, such songs of praise as would be celebrated by the people in times of signal deliverance (see the notes at Isaiah 12:1-6) This song of praise is one of the most beautiful that is to be found in the writings of Isaiah. The essential idea is that which was hinted at in Isaiah 24:23, that Yahweh would reign with a glory that would obscure the brightness of the sun and the moon on Mount Zion. Filled with the idea, the prophet fixes the eye on those future glories, and declares what shall occur under that reign. He sees Yahweh reigning there for a long series of years; and during that reign he sees Isaiah 25:6 that he would provide a way by which the darkness might be removed from all nations Isaiah 25:7; that he would originate that plan by which death would be swallowed up in victory Isaiah 25:8; and that there he would execute a plan by which all his enemies would be laid low Isaiah 25:9-12. The hymn is designed, therefore, to celebrate the faithfulness of God in fulfilling his ancient promises, and delivering his people from their long captivity by the destruction of Babylon Isaiah 25:1-5; and the future glories that would shine forth under the reign of Yahweh on Mount Zion, including the arrangements of redeeming mercy for the world.
