Exodus 15:20,21

Miriam the prophetess So called, either in a general sense, because she was an instructer of other women in the praise and service of God, or in a more special sense, because she had the spirit of prophecy, Numbers 12:2; Micah 6:4. Miriam (or Mary, for it is the same name) now presided in an assembly of the women, who, according to the common usage of those times, with timbrels and dances, sung this song. Moses led the sacred song, and gave it out for the men, and then Miriam for the women. Famous victories were wont to be applauded by the daughters of Israel, (1 Samuel 18:6,) so was this. When God brought Israel out of Egypt, it is said, (Micah 6:4,) he sent before them Moses, Aaron, and Miriam; though we read not of any thing remarkable that Miriam did but this. But those are to be reckoned great blessings to a people, that go before them in praising God. And Miriam answered them The men: they sung by turns, or in parts.
