Exodus 15:18
The LORD shall reign for ever and ever.
The LORD shall reign for ever and ever. Even that same Lord that is spoken of throughout this song, and to whom everything in it is ascribed, and who is no other than the Lord Jesus Christ; his reign began in eternity, when he was set up and anointed as King over God's holy hill of Zion, his church, the elect, who were a kingdom put under his care and charge, and which he will deliver up again one day, complete and perfect: he reigned throughout the whole Old Testament dispensation, and was acknowledged as well as prophesied of as a King; in his state of humiliation he had a kingdom, though not of this world, and upon his ascension to heaven he was made and declared Lord and Christ; and thenceforward his kingdom became very visible in the Gentile world, through the ministration of his word, accompanied by his almighty power; and ever since, more or less, he has ruled by his Spirit and grace in the hearts of many of the children of men, and, ere long, will take upon him his great power, and reign, in a more visible, spiritual, and glorious manner, in the midst of his churches, in the present state of things; and then he will reign with all his saints raised from the dead, for the space of a thousand years on earth, and after that will reign with them for ever in heaven, in the ultimate state of glory and happiness: the reigns of all others are but short, or, however, but for a time, but the reign of Christ is for ever and ever; the reigns of sin, and of Satan, and of death, have an end, but of the government of Christ, and the peace thereof, there will be no end; the reigns of the greatest potentates, emperors, and kings, of cruel and tyrannical princes, such as Pharaoh, are limited to a certain time, as is the reign of antichrist, which when ended, and the saints will have got the victory over him, the song of Moses and the Lamb will be sung; but Christ's kingdom is an everlasting kingdoms, and his dominion is evermore: the Targum of Jonathan is,
"let us set a crown on the head of our Redeemer, whose is the royal crown, and he is King of kings in this world, and whose is the kingdom in the world to come, and whose it is and will be for ever and ever;''
and to the same purpose is the Jerusalem Targum.
