It is logical that after such a victory over Egypt, joy and celebration would be experienced. For this reason, the most ancient traditions attribute to Moses this song that celebrates not only the miracle of liberation from Egypt (1-11) but also the Lord’s companionship through the desert, the gift of the land, and His enduring presence in it (12-18). Verses 20f correspond to another ancient tradition, according to which, after the deliverance, Miriam, Aaron’s sister, leads the women in a liturgy featuring tambourines and dances to celebrate the victory.
