John Wesley on Exodus 15:20

Miriam (or Mary, it is the same name) 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 psalm, 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, 1Sam 18:6,7, so was this. When God brought Israel out of Egypt, it is said, Mic 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.
