(Joseph Smith Prophesied) "by the authority of Jesus Christ that not many years shall pass away before the wicked of this generation will be swept from off the face of the land and the Lost Ten Tribes will be gathered to Missouri, and that The people of the Lord… have already commenced to gather together to Zion, which is in the state of Missouri; therefore I declare unto you the warning which the Lord has commanded me to declare unto this generation…. The hour of His judgment is Come. He exhorts all to Flee to Zion, before the overflowing scourge overtake you, for there are now those living upon the earth whose eyes shall not be closed in death until they see all these things, which I have spoken, fulfilled."
