Exodus 15:1-18

The "song of Moses" (Exodus 15:1-18) points to the song of victory sung by Moses and the Israelites after their passage through the Red Sea. This song may be the one sung on the sea of glass. It is referring to the Red Sea crossing that spiritually symbolizes the process of salvation from God's calling to our baptism, overcoming, leaving sin behind, and entering God's kingdom.

The ancient "song of Moses" is fulfilled in the future "song of the Lamb," which tells of a greater redemption of a new kingdom of priests: the bride of Christ. Essentially, this song pictures the majesty, holiness, and purity of God. A later song of Moses praised the Lord whose ways are just. That song of Moses is found in Deuteronomy 32:1-43 (note especially verse 4).

Exodus 15:11-12

The song of Moses is specifically about God's single action of delivering Israel from the destruction of Egypt and freeing them from slavery. But Moses, under God's inspiration, is fully aware that he is writing a song with wider application, and the point that he uses, the plural praises and wonders, indicates that he is very much aware of that. He is writing a song that will be relevant to God's people over the centuries as they sing praises to the King, having witnessed the various wonders that He has performed for them in their respective circumstances.
