“The Rebellious Are Not of the Blood of Ephraim”
Doctrine and Covenants 64:35–36
35 And the rebellious shall be cut off out of the land of Zion, and shall be sent away, and shall not inherit the land.
36 For, verily I say that the rebellious are not of the blood of Ephraim, wherefore they shall be plucked out.
President Joseph Fielding Smith said:
“It is essential in this dispensation that Ephraim stand in his place at the head, exercising the birthright in Israel which was given to him by direct revelation. Therefore, Ephraim must be gathered first to prepare the way, through the gospel and the priesthood, for the rest of the tribes of Israel when the time comes for them to be gathered to Zion.”
