Nehemiah 10:15

Bunni, Azgad, Bebai,

Bunni, Azgad, and Bebai were among the remnant connected with Jerusalem after the seventy-year captivity. The chapter to which their names belong records the condition of that remnant and those who entered into a covenant.

That covenant was a covenant to keep the law of Moses. In entering it, the people established the Pentateuch as the canonical and authoritative book of the Jews.
