Exodus 15

Exodus 15 follows the Red Sea crossing with what the chapter records as its proper response: worship. The chapter’s first eighteen verses are the Song of Moses — shirat hayam, “the song of the sea” — one of the OT’s earliest preserved Hebrew compositions and the canonical scriptural model for redemption-historical praise. The chapter then records Miriam’s responsive antiphon (15:20-21) and the first wilderness murmuring at Marah (15:22-27).

The Song of Moses (15:1-18). The Song’s opening refrain — “I will sing unto the LORD, for he hath triumphed gloriously: the horse and his rider hath he thrown into the sea” — is the song’s structural keynote and the line Miriam will sing back to the women. The composition has a three-movement structure widely recognized in scholarship: deliverance at the sea (15:1-12), conquest-foreshadowing as the nations hear (15:13-17), and the LORD’s eternal reign (15:18 — “The LORD shall reign for ever and ever”).

The first movement (15:1-12) is the chapter’s most concentrated celebration of the LORD’s right hand: “Thy right hand, O LORD, is become glorious in power: thy right hand, O LORD, hath dashed in pieces the enemy.” The recurring right hand יָמִין yamin Hebrew ‘Right hand.’ The OT's standard image of divine power and favor (Ps 16:11, 17:7, 18:35, 20:6, 44:3, 48:10, 60:5, 63:8, 78:54, 89:13, 98:1, 110:1, 118:15-16, 138:7). The Song of Moses establishes the image at the Exodus's structural climax; its recurrence in the Psalms and prophets becomes one of the OT's most consistent stable images of YHWH's saving action. Christ's session ‘on the right hand of God’ (Mark 16:19; Acts 7:55-56; Heb 1:3, 10:12) takes up the same vocabulary. imagery establishes the OT’s standard vocabulary for divine power that the Psalms and prophets will return to repeatedly. The cosmological imagery — “with the blast of thy nostrils the waters were gathered together, the floods stood upright as an heap” — pictures the LORD’s wind-instrument of Exodus 14:21↗ in mythic enlargement. The first movement closes with the comparative-incomparable hymn-question: “Who is like unto thee, O LORD, among the gods? who is like thee, glorious in holiness, fearful in praises, doing wonders?” The interrogative form — mi-kamokha in Hebrew — becomes the OT’s distinctive vocabulary for radical monotheism and is the source of the name Michael (“Who is like God?”).

The second movement (15:13-17) foreshadows the conquest. The LORD has led His people in mercy, has guided them in strength “unto thy holy habitation”; the nations will hear and tremble (“the dukes of Edom shall be amazed; the mighty men of Moab, trembling shall take hold upon them; all the inhabitants of Canaan shall melt away”). The movement closes with the sanctuary-arrival: “Thou shalt bring them in, and plant them in the mountain of thine inheritance, in the place, O LORD, which thou hast made for thee to dwell in.” The Sinai and eventual Zion / tabernacle / temple are all in view; the chapter is unfolding the entire Exodus-to-temple trajectory in poetic anticipation.

The third movement (15:18) is the Song’s one-verse climax: “The LORD shall reign for ever and ever.” The Hebrew imperfect verb (yimlokh) takes on durative-eternal force in the construction l’olam wa’ed (“for ever and ever”). The verse becomes one of the OT’s most distilled formulations of divine kingship; Revelation 11:15↗ (“The kingdoms of this world are become the kingdoms of our Lord, and of his Christ; and he shall reign for ever and ever”) deliberately echoes it at the eschatological climax. Revelation 15:3↗ takes the further step of joining the Song of Moses with the song of the Lamb in the redeemed multitude’s worship: “And they sing the song of Moses the servant of God, and the song of the Lamb, saying, Great and marvellous are thy works, Lord God Almighty; just and true are thy ways, thou King of saints.” The Exodus 15 hymn becomes the eschatological hymn of the redeemed.

Miriam’s antiphon (15:19-21). The chapter pauses to set the scene — “the horse of Pharaoh went in with his chariots and with his horsemen into the sea, and the LORD brought again the waters of the sea upon them; but the children of Israel went on dry land in the midst of the sea” — and then turns to Miriam. The OT’s first use of prophetess נְבִיאָה nevi'ah Hebrew ‘Prophetess.’ Miriam's title in 15:20 is the OT's first formal naming of female prophetic office. Later OT prophetesses: Deborah (Judg 4:4), Huldah (2 Kgs 22:14), Noadiah (Neh 6:14, named negatively), the wife of Isaiah (Isa 8:3); Anna appears in the NT (Luke 2:36). The chapter establishes Miriam as a public-worship leader: she takes the timbrel, the women follow her with timbrels and dances, she sings the Song's opening refrain antiphonally. Micah 6:4 will list Miriam with Moses and Aaron as one of the three the LORD sent to lead Israel out of Egypt. names Miriam (“the prophetess, the sister of Aaron”). She takes a timbrel; all the women go out after her with timbrels and dances; she sings the Song’s opening refrain antiphonally: “Sing ye to the LORD, for he hath triumphed gloriously; the horse and his rider hath he thrown into the sea.” The chapter records the entire community’s worship — Moses and the men singing the Song, Miriam and the women singing the antiphon — without comment on the gender division, simply recording the scene as it stands.

Marah and the first wilderness murmuring (15:22-27). The chapter’s tone shifts immediately. Three days into the wilderness of Shur, Israel finds no water; at Marah, the waters are bitter (“therefore the name of it was called Marah מָרָה marah Hebrew ‘Bitter.’ The same root appears in the place-name Marah and in Naomi's later renaming herself ‘Mara’ at Ruth 1:20 (‘call me not Naomi, call me Mara: for the Almighty hath dealt very bitterly with me’). The Hebrew name of the place names what is wrong with the water — etymological place-names are a recurring OT pattern (Bethel ‘house of God,’ Beersheba ‘well of the oath,’ Massah ‘testing’). ”). The people murmur. The chapter establishes the pattern that will run through the next chapters: deliverance, immediate hardship, complaint, divine provision. Moses cries unto the LORD; the LORD shows him “a tree” which he casts into the waters; the waters become sweet.

The Marah encounter then becomes the occasion for the chapter’s most theologically dense statement. The LORD makes the people a choq u’mishpat (a statute and an ordinance) and “proved them” — the wilderness will be the people’s testing-ground (cf. Deuteronomy 8:2–3↗ “to humble thee, and to prove thee”). The chapter then records the divine self-naming that the wilderness statute culminates in: “If thou wilt diligently hearken to the voice of the LORD thy God, and wilt do that which is right in his sight, and wilt give ear to his commandments, and keep all his statutes, I will put none of these diseases upon thee, which I have brought upon the Egyptians: for I am the LORD that healeth רָפָא rapha Hebrew ‘To heal.’ The verb behind YHWH-rofecha (‘the LORD that healeth thee’) in 15:26. Rapha runs through the OT as the standard healing-verb: of personal restoration (Gen 20:17, Job 5:18, Ps 6:2, 30:2, 41:4, 103:3, 147:3), of national restoration (Isa 19:22, 53:5 the Suffering Servant ‘with his stripes we are healed’; Jer 3:22, 17:14; Hos 6:1), of cosmic restoration (Mal 4:2 ‘the Sun of righteousness arise with healing in his wings’). Jesus' healing ministry in the Gospels is reported in language that consciously echoes the rapha-vocabulary, especially Matthew's repeated formulae of OT-fulfillment. thee.” The Exod 15:26 self-naming joins YHWH-Yireh (Genesis 22:14↗), El Shaddai (Exodus 6:3↗), and the chain of YHWH-divine-name compounds that will accumulate through the wilderness and into the prophets. The chapter closes with Israel encamped at Elim — twelve wells, seventy palms — the journey’s first place of rest.
