Blayney was educated at Oxford, took a master's degree in 1753, and became fellow and vice-principal of Hertford College in 1768. He was employed by the Clarendon Press to prepare a corrected edition of the King James Version of the Bible. This appeared in 1769, but most of it was destroyed by fire in the Bible warehouse, Paternoster Row, London. Blayney then studied Hebrew; he received the degree of D.D., was appointed regius professor of Hebrew in 1787, and was made canon of Christ Church, Oxford.
