The Cambridge Bible for Schools and Colleges
The Cambridge Bible for Schools and Colleges is a biblical commentary set published in parts by Cambridge University Press from 1882 onwards. Anglican bishop John Perowne was the general editor. The first section published was written by theologian Thomas Kelly Cheyne and covered the Book of Micah.
Perowne exercised limited editorial control over the writers of individual commentaries: his aim was "to leave each contributor to the unfettered exercise of his own judgment".
