In the 1780's, the Baptist pastor John Leland was fighting against Virginia state taxes going to support the Episcopalian clergy. One clergyman argued that they had to have the tax income in order to have the time needed to prepare for sermons. Leland responded that he could expound the scriptures without special preparation and the Episcopalian challenged him to prove it by preaching on a text provided just before the sermon. "Leland went into the pulpit and was handed a text which proved to be Numbers 22:21And Balaam rose up in the morning, and saddled his ass, and went with the princes of Moab.
See All..., 'And Balaam saddled his ass.' Mr Leland first commented on the account from which the text was taken, and then said he should divide his subject into three parts: 1st, Balaam, as a false prophet, represents a hireling clergy; 2nd, the saddle represents their enormous salaries, and 3rd, the dumb ass represents the people who will bare such a load."
