Shabbethai
Shabbethai is the name of one or more Levites active in the post-exilic restoration. The references gather around two scenes: the resolution of the foreign-marriage crisis under Ezra, and the public reading of the law under Nehemiah, with a further notice placing a Shabbethai among the chiefs of the Levites at the temple.
Levite in Ezra's Reform
When the assembly weighs the action against the foreign marriages, only a small minority objects to the proceeding. Among those who side with the dissenters and help them stands a Levite by this name: "Only Jonathan the son of Asahel and Jahzeiah the son of Tikvah stood up against this [matter]: and Meshullam and Shabbethai the Levite helped them" (Ezr 10:15).
Expounder of the Law under Nehemiah
In the great public reading of the law at the Water Gate, a Shabbethai is named among the Levites who explained the text to the gathered people: "Also Jeshua, and Bani, and Sherebiah, Jamin, Akkub, Shabbethai, Hodiah, Maaseiah, Kelita, Azariah, Jozabad, Hanan, Pelaiah, and the Levites, caused the people to understand the law: and the people [stood] in their place" (Ne 8:7).
Chief Levite over Outward Business
A Shabbethai is also placed among the senior Levites assigned to administrative oversight at the temple: "and Shabbethai and Jozabad, of the chiefs of the Levites, who had the oversight of the outward business of the house of God" (Ne 11:16). The pairing with Jozabad recurs and the role is the external administration of the temple — the work outside the inner courts.
