“In due course the Lost Tribes of Israel will return and come to the children of Ephraim to receive their blessings. This great gathering will take place under the direction of the President of The Church of Jesus Christ of Latter-day Saints, for he holds the keys. … Keys are the right of presidency, the power to direct; and by this power the Lost Tribes will return, with ‘their prophets’ and their scriptures to ‘be crowned with glory, even in Zion, by the hands of the servants of the Lord, even the children of Ephraim.’ (D. & C. 133:26–35.)” (Mormon Doctrine, 2nd ed. [1966], 457–58; see also Doctrine and Covenants Student Manual, 2nd ed. [Church Educational System manual, 2001], 340–41).
