Nehushta (נְחֻשְׁתָּא) is from the Hebrew nechosheth (bronze, brass). In 2 Kings 24:8, Nehushta was the daughter of Elnathan and the mother of King Jehoiachin of Judah — taken into Babylonian exile with her son in 597 BCE.
Rare but iconic in biblical scholarship.
Nehushta reduces to three — the number of biblical queen-mother.
