This book explores the importance of the tribes of Ephraim, Manasseh, and all of the lost tribes to Biblical and Book of Mormon prophecy regarding the establishment of Zion in the last days. In the restoration of all things, spoken of by the prophets of old, God will bring about the restoration of the whole House of Israel, gather the lost tribes to a place of refuge, and set up an ensign for a witness to the world--a city set on a hill, from which servants of God will go forth and preach the gospel with power and the Holy Ghost.
