What is "bithiah"

Bithiah ( Biṯyāh, literally "daughter of Yah") was an Egyptian princess, and a daughter of Pharaoh according to Hebrew tradition. Although the name of her father is not stated in the Hebrew Bible, she is said by Rabbinic Midrash to be the daughter of one of the Pharaoh of the Exodus. The Bible and Midrash both assert that she was the foster mother of Moses, having drawn him from the Nile and bestowed upon him his name, which in Hebrew meant 'drawn out' .

In Jewish tradition, she was exiled by the Pharaoh for bringing Moses the Levite into the house of Pharaoh and claiming him as her own child. Bithiah left Egypt with Moses during the mass Exodus of the children of Israel. She married Mered the Judahite. Her children were Miriam, Shammai, and Ishbah (the father of Eshtemoa).
