David Whitmer recalls revelation through the seer stone.
David Whitmer, An Address to All Believers in Christ by a Witness to the Divine Authenticity of The Book of Mormon (Richmond, MO: David Whitmer, 1887), 31
Brother Hyrum said it had been suggested to him that some of the brethren might go to Toronto, Canada, and sell the copy-right of the Book of Mormon for considerable money: and he persuaded Joseph to inquire of the Lord about it. Joseph concluded to do so. He had not yet given up the stone. Joseph looked into the hat in which he placed the stone, and received a revelation that some of the brethren should go to Toronto, Canada, and that they would sell the copy-right of the Book of Mormon. Hiram Page and Oliver Cowdery went to Toronto on this mission, but they failed entirely to sell the copy-right, returning without any money. Joseph was at my father's house when they returned. I was there also, and am an eye witness to these facts. Jacob Whitmer and John Whitmer were also present when Hiram Page and Oliver Cowdery returned from Canada. Well, we were all in great trouble; and we asked Joseph how it was that he had received a revelation from the Lord for some brethren to go to Toronto and sell the copy-right, and the brethren had utterly failed in their undertaking. Joseph did not know how it was, so he enquired of the Lord about it, and behold the following revelation came through the stone: "Some revelations are of God: some revelations are of man: and some revelations are of the devil."
