Sing unto God, ye kingdoms of the earth,.... Not only the Egyptian and Ethiopian kingdoms, but all the kingdoms of the world; which will now be converted to Christ, and become his, even all the Papal, Pagan, and Mahometan kingdoms; see Re 11:15.
These are called upon to sing songs and hymns of praise to Christ, who is God, for redemption by him, and salvation in him; and for their deliverance from all the darkness and delusions under which they formerly were;O sing praises unto the Lord; the Lord of all, the Lord of lords, the Head of the church, and Saviour of the body; and whom those converted nations will acknowledge to be their Lord and King; and make their homage, and bring their tribute of praise to him, for breaking the antichristian yokes that were upon them, and freeing them from the tyranny and bondage with which they were oppressed: this will be fulfilled in the latter day; see Re 11:1.
