sentences:  Bethune was forced to travel to Pisa to secure an order from Innocent II declaring that the chapter obey their bishop.Around 1142, Bethune was involved with a conflict with Miles of Gloucester, who was now the Earl of Hereford, which led to the bishop excommunicating Miles and all the inhabitants of the city of Hereford, and "had the doors of the church blocked with thorns and the crosses taken down and placed on the ground".This dispute arose over an attempt by Miles to tax the churches in his earldom, which Bethune regarded as unlawful.
