Exodus 15:18

The Lord shall reign for ever and ever. Similar declarations are found elsewhere in Scripture (see Ps. 10:16; 29:10; 146:10; Rev. 11:15; etc.). Moses thus expresses the firm conviction of the man of God that God’s dominion is everlasting, not alone in the universe but in this world as well, not only under the law but also under the gospel, not only in time but throughout eternity. With this inspired exclamation the song of Moses closes, though in the next verse he gives an explanation of why God’s reign will last forever.

Like the two preceding stanzas, which ended with a statement concerning the destruction of the Egyptians (see vs. 5, 10), the third is brought to a close in a similar way. Instead of directing attention to the defeated Egyptians, however, Moses turns to their own triumphant Deliverer. The song, therefore, does not close with a gloomy picture of the destruction of God’s enemies, but on a note of victory and praise. This same theme will characterize the song of Moses and the Lamb, which the redeemed will sing upon the sea of glass (Rev. 15:2-4).
