From The New Schaff-Herzog Encyclopedia of Religious Knowledge, Vol. III: Chamier - Draendorf entry on Adam Clarke (pg 126) (emphasis added):

… He served in various places and traveled throughout Great Britain, achieving fame as a preacher, and being president of the British Conference in 1806, 1814, and 1822. 1814, and 1822. …

… The most important of his numerous works was his Commentary on the Bible (8 volumes, Liverpool, 1810–26), which long had an extensive circulation. …

He is sometimes noted as “perhaps the most famous Methodist/Wesleyan commentator to date.”
