The celebration of the Israelites' rescue at the sea reaches its peak as profound spiritual joy spreads through the camp. Miriam steps forward to lead the women in their own song, highlighting their essential role in the miracle and offering a unique perspective on thanking God. The primary approach among commentators is that this was a musical call-and-response, where Miriam sang a line and the women answered her [רש״י, שד״ל, אבן עזרא, גור אריה]. Others suggest that their song served as a chorus, echoing after each section sung by the men [העמק דבר, קאסוטו]. While the historical record only captures a brief fragment of her words, commentators agree that Miriam actually sang the entire song of praise for the women, mirroring exactly what Moses did, with the text simply summarizing the full event.
The nature of Miriam's response carries deeper layers of meaning. Some explain that she was directly answering women who mistakenly thought the tambourines were brought to celebrate the physical wealth washing ashore, clarifying that their joy was entirely spiritual [שפתי כהן]. Other traditions focus on who was being addressed, as the original text uses a masculine form to describe her audience. This might indicate that the women were responding directly to Moses and the men [שד״ל, ביאור יש״ר], or that Miriam was answering ministering angels who wondered why the women were singing so early [ריב״א, חתם סופר]. She may have even been answering men who questioned her use of a tambourine [פרדס יוסף]. A powerful alternative perspective suggests that the masculine phrasing was directed at the women themselves to highlight a moment of absolute spiritual equality. The revelation of God was so intense and brought about such overwhelming awe that men and women could sing in the same space without any concern for inappropriate thoughts [רש״ר הירש, נחל קדומים, חומת אנך].
Miriam's specific focus on the drowning of the Egyptian horses and riders holds profound significance. The women sang with the deep recognition that the miracle of survival occurred specifically because of their own merit [מלבי״ם]. In fact, because the righteousness of the women was so great, the rescue of the Israelites was practically guaranteed. Therefore, the true wonder worthy of a song was not the survival itself, but the supernatural punishment of their enemies [חתם סופר]. The specific mention of the horse serves to highlight the greatness of the women. Just as a horse, which merely assists its rider, was punished alongside him in the sea, the same principle applies to positive actions. Women, though exempt from formal Torah study, actively support and encourage their families to learn. Because of this vital support, they receive the exact same reward as if they had studied themselves [פרדס יוסף]. Through this unified praise, the women were elevated to the level of a completely new creation, finding full forgiveness for their past mistakes [שפתי כהן].
