Miriam

Miriam (Hebrew: מִרְיָם, Modern Miryam, Tiberian Miryām; see Miriam (given name)), according to the Hebrew Bible or Old Testament, was the daughter of Amram and Yocheved, and the sister of Moses and Aaron. She was a prophet and first appears in the Book of Exodus.

Miriam was the daughter of Amram, the leader of the Israelites in ancient Egypt, and of Yocheved, who was so righteous she was exempt from the curse of Eve. Both Amram and Yocheved were from leading families of the illustrious Tribe of Levi. As such, Miriam was also the sister of Aaron and Moses. The Torah refers to her as “Miriam the Prophetess” and the Talmud names her as one of the seven major female prophets of Israel. Scripture describes her alongside of Moses and Aaron as delivering the Jews from exile in Egypt: “For I brought you up out of the land of Egypt and redeemed you from the house of slavery, and I sent before you Moses, Aaron, and Miriam”. According to the Midrash, just as Moses led the men out of Egypt and taught them Torah, so too Miriam led the women and taught them Torah.

Miriam was the oldest child of Amram and Yocheved. According to the Midrash, just as Aaron was three years older than Moses, so too Miriam was three years older than Aaron. Thus Miriam was three years older than Aaron and six years older than Moses.

Although there are various opinions throughout Talmudic sources regarding Miriam’s spouse, the most commonly accepted opinion is that she was the wife of Calev and thus the mother of Hur (mentioned in Exodus as a disciple of Moses). Calev’s wife is also identified as Efrat, meaning “fruitful”. This suggests that Miriam, as the wife of Calev, had at least two names - Miriam and Efrat (she actually had many names, see below). For this reason, when naming a girl Miriam, traditionally both names are conjoined to become Miriam Efrat, since, by sparing Jewish children from Pharaoh’s wicked decree, Miriam caused Israel to be fruitful and multiply.
