[Apostle Wilford Woodruff Journal] ... The People are much stired up in Manchester. Their will soon be persecution arise against the Saints in this town. The work is progressing. The servants of God have preached in the streets, & the town is warned & the methodist Preachers are much stired up against it. They gathered together at a house & sent for a young Brother, a Priest, by the name of James Mahon who had the gift of tongues to come & meet them & speak to them in Hebrew & if he did not speak to them correctly in Hebrew they would rise up against the work & try to overthrow it.
