A remarkable name meaning possibly 'daughter of Yahweh' or 'worshipper of Yah,' given to an Egyptian princess who married into the tribe of Judah. The name follows a pattern seen in Phoenician (בתבעל, 'daughter of Baal'), where 'bat' (daughter) compounds with a divine name to indicate devotion. That an Egyptian royal bore a Yahwistic name suggests either conversion or that the name was given later, commemorating her incorporation into Israel. She is explicitly identified as Pharaoh's daughter.
