Studies in Scripture 3:63; “The chances are probably more than nine out of ten that you and I are the lineal blood descendants of Joseph, the son of Jacob. In fact, “Nearly every member of the Church is undoubtedly a literal blood descendant of Jacob.” More specifically, President Joseph Fielding Smith explained, “At the present time most of those who are receiving the Gospel are of the tribe of Ephraim [son of Joseph].””
Isaiah 59:4-8; “None calleth for justice, nor any pleadeth for truth: they trust in vanity, and speak lies; they conceive mischief, and bring forth iniquity. 5 They hatch cockatrice’ eggs, and weave the spider’s web: he that eateth of their eggs dieth, and that which is crushed breaketh out into a viper. 6 Their webs shall not become garments, neither shall they cover themselves with their works: their works are works of iniquity, and the act of violence is in their hands. 7 Their feet run to evil, and they make haste to shed innocent blood: their thoughts are thoughts of iniquity; wasting and destruction are in their paths. 8 The way of peace they know not; and there is no judgment in their goings: they have made them crooked paths: whosoever goeth therein shall not know peace.”
There are no members of the tribe of Ephraim left. God told us as much in the book of Obadiah.
