"The song is composed of three gradually increasing strophes, each of which commences with the praise of Jehovah, and ends with a description of the overthrow of the Egyptian host (vv. 2-5, 6-10, 11-18). The theme announced in the introduction in v. 1 is thus treated in three different ways; and whilst the omnipotence of God, displayed in the destruction of the enemy, is the prominent topic in the first two strophes, the third depicts with prophetic confidence the fruit of this glorious event in the establishment of Israel, as a kingdom of Jehovah, in the promised inheritance."248
Cassuto divided the strophes better, I believe, as vv. 1-6, vv. 7-11, and vv. 12-16, with an epilogue in vv. 17-18.249Kaiser proposed a similar division: 1b-5, 6-10, 11-16a, and 16b-18.250
"It is not comparable to any one psalm, or song or hymn, or liturgy known to us anywhere else in the OT or in ANE literature."251
"Yahweh is both the subject and the object of this psalm; the hymn is about him and to him, both here and in the similar usage of Judg 5:3 . . ."252
It is interesting that Moses described the Egyptian pursuers as being thrown into the sea (v. 4) and sinking like a stone (v. 5) and lead (v. 10). The same image describes Pharaoh's earlier order to throw the Hebrew babies into the Nile River (1:22). God did to the Egyptians what they had done to the Israelites.253
This hymn is a fitting climax to all God's miracles on behalf of the Israelites in leading them out of Egypt. It is a song of praise that focuses on God Himself and attributes to Him the superiority over all other gods that He had demonstrated (cf. v. 11). Undoubtedly the Israelites sang this inspired song many times during their wilderness wanderings and for generations from then on.254The first part of the song (vv. 1-12) looks back on God's destruction of the Egyptian soldiers, and the second part (vv. 13-18) predicts Israel's entrance into the Promised Land. The divine name appears ten times.
"The event at the Red Sea, when the Egyptian army was drowned, was celebrated as a great military victory achieved by God (Exodus 15:1-12). It was that event, wherein a new dimension of the nature of God was discovered by the Hebrews (the new understanding is expressed forcefully by the explanation the Lord is a man in battle' [v. 3]), that opened to their understanding the real possibility, if not necessity, of taking possession of the promised land by means of military conquest (Exodus 15:13-18)."255
"The Exodus was one of the foundational events of Israel's religion. It marked the liberation from Egyptian slavery, which in turn made possible the formation of a relationship of covenant between Israel and God. And nowhere is the Exodus given more powerful expression than in the Song of the Sea (Exodus 15:1-18), a great victory hymn celebrating God's triumph over Egypt at the sea. To this day, the ancient hymn continues to be employed in the synagogue worship of Judaism. Its continued use reflects the centrality of its theme, that of God's control over the forces of both nature and history in the redemption of his people.
"When one reads the Song of the Sea, one immediately gains an impression of the joy and exhilaration expressed by those who first used its words in worship. But what is not immediately evident to the modern reader is the subtle manner in which the poet has given force to his themes by the adaptation of Canaanite mythology. Underlying the words and structure of the Hebrew hymn are the motifs of the central mythology of Baal; only when one understands the fashion in which that mythology has been transformed can one go on to perceive the extraordinary significance which the poet attributed to the Exodus from Egypt.
"The poet has applied some of the most central motifs of the myth of Baal. These motifs may be summarized in certain key terms: conflict, order, kingship, and palace-construction. Taking the cycle of Baal texts as a whole (see further Chapter IV), the narrative begins with conflict between Baal and Yamm (Sea'); Baal, representing order, is threatened by the chaotic Yamm. Baal's conquest of Yamm marks one of the steps in the process of creation; order is established, and chaos is subdued. Baal's victory over Yamm is also the key to his kingship, and to symbolize the order and consolidate the kingship, Baal initiates the construction of his palace. And then, in the course of the myth, conflict breaks out again, this time between Baal and Mot. Baal is eventually victorious in this conflict, establishing once again his kingship and the rule of order. It is important to note not only the centrality of these motifs in the Baal myth, but also their significance; the motifs as a whole establish a cosmological framework within which to interpret the Baal myth. It is, above all, a cosmology, developing the origins and permanent establishment of order in the world, as understood and believed by the Canaanites. Its central celebration is that of creation.
"In the Song of the Sea, the poet has developed the same central motifs in the structure of his song. The song begins with conflict between God and Egypt (Exodus 15:1-12), but the way in which the poet has transformed the ancient motifs is instructive. Sea' is no longer the adversary of order, but God uses the sea (Hebrew yam) as an instrument in the conquest of chaos. After the conquest, God is victorious and establishes order; his kingship is proclaimed in a statement of his incomparability (verse 11). But then the theme of conflict is resumed again, as future enemies are anticipated (verses 14-16). They, too, would be conquered, and eventually God's palace and throne would be established as a symbol of the order achieved in his victory (verse 17). Finally, God's kingship would be openly declared, as a consequence of his victories: the Lord shall reign for ever and ever' (verse 18). The Hebrew expression for this statement of kingship is yhwh ymlk, directly analogous to the celebration of Baal's kingship in the Ugaritic texts: b'l ymlk.
"It is one thing to trace the motifs of the Baal myth in the Song of the Sea; it is another to grasp their significance. The primary significance lies in the cosmological meaning of the motifs; the Hebrew poet has taken the symbolic language of creation and adapted it to give expression to his understanding of the meaning of the Exodus. At one level, the Exodus was simply the escape of Hebrews from Egyptian slavery; at another level, it marked a new act of divine creation. Just as Genesis 1 celebrates the creation of the world, so too Exodus 15 celebrates the creation of a new people, Israel. And when one perceives this underlying significance of the poetic language employed in the Song of the Sea, one is then in a position to understand better another portion of the biblical text, namely, the reasons given for the observation of the sabbath day."256
"Throughout the poem, however, the picture of God's great deeds foreshadows most closely that of David, who defeated the chiefs of Edom, Philistia, and Canaan and made Mount Zion the eternal home for the Lord's sanctuary (v. 17)."257
"The poem of Exod 15 celebrates Yahweh present withhis people and doing forthem as no other god anywhere and at any time canbe present to do. As such, it is a kind of summary of the theological base of the whole of the Book of Exodus."258
Worship was the result of redemption. The people looked back at their deliverance and forward to God's Promised Land. At this point their joy was due to their freedom from slavery. However the desert lay ahead. The family of Abraham had become a nation, and God was dwelling among them in the cloud. God's presence with the nation introduced the need for holiness in Israel. The emphasis on holiness begins with God's dwelling among His people in the cloud. It increased when God descended on the tabernacle and ark.
The parallel that exists between Abraham's experiences and Israel's is also significant. God first called Abram out of pagan Ur. Then He blessed him with a covenant after the patriarch obeyed God and went where Yahweh led him. God did the same thing with Israel. This similarity suggests that God's dealings with both Abram and Israel may be programmatic and indicative of His method of dealing with His elect generally.
