Miriam is the tritagonist of the 1998 film The Prince of Egypt.
She is the daughter and oldest child of Yocheved and the older sister of Aaron and Moses. When Moses was a baby, their mother Yocheved set Moses adrift in a basket. A young Miriam followed the basket where it ended up at the palace. Moses was found by the Queen and raised as her own son. When Miriam became an adult she met her brother and revealed he was a Hebrew. In the end Miriam leaves Egypt with her brothers and sings. Miriam was the only one to help her brother when every one was mean to him when he was trying to help.
Miriam is voiced by Eden Riegel (who also voiced Kiara in The Lion Guard) as a child and Sandra Bullock (Sally Dworsky (who was also the singing voice for Adult Nala in The Lion King) singing) as an adult.
