How did Israel sing the Song of the Sea after they crossed the Sea of Reeds and who sang it? TB Sotah 30-31

With the exception of Revelation upon Mount Sinai, no other event in the Torah captured the rabbis’ imagination than the splitting of the Sea of Reeds after leaving Egypt and slavery behind the Jewish people.  Rashi commenting on the verse writes: “This is my God” (Exodus 15:2) quotes the midrash. “In His glory did He reveal Himself to them and they pointed to Him — as it were — with the finger exclaiming “This is my God!” (Shir HaShirim Rabbah 3:15) A maid servant beheld at the Red Sea what even the prophets never saw (Mekhilta d'Rabbi Yishmael 15:2:2).” (Sefaria.org translation) How did the Israelites actually sing the Song of the Sea? There are three different opinions.

“The Sages taught: On that same day Rabbi Akiva taught that at the time that the Jewish people ascended from the split sea they set their eyes on reciting a song of gratitude to God. And how did they recite the song? In the same manner as an adult man reciting hallel on behalf of a congregation, as his reading enables all who hear to fulfill their obligation, and the congregation listening merely recite after him the chapter headings of hallel. So too, by the sea, Moses said: “I will sing unto the Lord” (Exodus 15:1), and the people said after Moses: “I will sing unto the Lord.” Moses continued and said: “For He is highly exalted” (Exodus 15:1), and they said once again the chapter heading: “I will sing unto the Lord.”

“Rabbi Eliezer, son of Rabbi Yosei HaGelili, says: The Jewish people sang just like a minor boy reciting hallel and the congregation who hear him repeat after him all that he says, word for word, as hearing the recital of a minor is insufficient for fulfilling one’s obligation. So too, by the sea, Moses said: “I will sing unto the Lord” (Exodus 15:1), and the people said after Moses: “I will sing to the Lord.” Moses said: “For He is highly exalted,” and they said after him the same words: “For He is highly exalted.”

 

“Rabbi Neḥemya says: They sang the song of the sea like a scribe, a cantor, who recites aloud the introductory prayers and blessings before Shema in the synagogue; as he begins by saying the first words of the blessing, and they repeat after him the initial words and continue reciting the rest of Shema together with him in unison. So too, in the song of the sea, Moses began and then everyone recited the entire song together with him.

“The Gemara asks: With regard to what do they disagree? The Gemara answers that they disagree with regard to the interpretation of the verse: “Then Moses and the children of Israel sang this song unto the Lord, and said, saying” (Exodus 15:1). Rabbi Akiva holds that the word “saying,” which indicates that the people sang after Moses, is referring only to the first words of the song, which the people continually repeated: “I will sing unto the Lord” (Exodus 15:1).

“And Rabbi Eliezer, son of Rabbi Yosei HaGelili, holds that the word “saying” is referring to every single word, as they would repeat after Moses every word. And Rabbi Neḥemya holds that the phrase “and they said” (Exodus 15:1) indicates that everyone recited the song of the sea together, and the word “saying” means that Moses began singing the song first; and then the rest of the people sang the beginning after him and they all continued in unison.

“The Sages taught in a baraita that Rabbi Yosei HaGelili taught: At the time that the Jewish people ascended from the sea they resolved to sing a song of gratitude to God. And how did they recite this song? If a baby was lying on his mother’s lap or an infant was nursing from his mother’s breasts, once they saw the Divine Presence, the baby straightened his neck and the infant dropped the breast from his mouth, and they recited: “This is my God and I will glorify Him” (Exodus 15:2). As it is stated: “Out of the mouths of babies and sucklings You have founded strength” (Psalms 8:3).  "Rabbi Meir would say: From where is it derived that even fetuses in their mother’s womb recited the song at the sea? As it is stated: “In full assemblies, bless God, the Lord, you that are from the source of Israel” (Psalms 68:27), indicating that even children that are in the “source,” i.e., their mother’s womb, blessed God when they gathered at the sea.

“The Gemara asks: But the fetuses could not see, so how could they have honestly said: “This is my God and I will glorify him”? Rabbi Tanḥum says: Their mother’s stomach was transformed for them like luminous crystal [aspaklarya], and they saw through it.” (Sefaria.org translation)

As you can see, the entire people were so grateful for God’s salvation everybody, man, woman, child, and even the fetus in the womb sang out loud.

Every morning we to sing the Song of the Sea and hopeful expectation that just as God saved our people at the shore of the Sea of Reeds, so too will the Holy One redeem his people speedily in our day.
