(rebellion), the sister of Moses, was the eldest of that sacred family, and she first appears, probably as a young girl, watching her infant brother’s cradle in the Nile (Exodus 2:4) and suggesting her mother as a nurse (Exodus 2:7). After the crossing of the Red Sea “Miriam the prophetess” is her acknowledged title (Exodus 15:20). The prophetic power showed itself in her under the same form as that which it assumed in the days of Samuel and David—poetry, accompanied with music and processions (Exodus 15:1-19). She took the lead, with Aaron, in the complaint against Moses for his marriage with a Cushite (Numbers 12:1-2), and for this was attacked with leprosy. This stroke and its removal, which took place at Hazeroth, form the last public event of Miriam’s life (Numbers 12:1-15). She died toward the close of the wanderings at Kadesh and was buried there (Numbers 20:1).
