Isaac, Israel's (AKA Jacob) dad had only one wife, Rebekah.
You are correct. Sorry about the mistake.
Have you seen this chart? If I recall you were looking into ‘the sons of Zarah’.
I think Utah Girl is speaking about the teaching in LDS circles that Abraham, Isaac and Jacob(Israel) are now polygamists who are now exalted. I'd suggest searching on ISAAC in the Journal of Discourses to find some references on this. And also look at http://scriptures.lds.org/en/dc/132/1#1 and http://scriptures.lds.org/en/dc/132/37#37.
In summary I'd like to mention that there is only one big issue that separated the LDS from the FLDS theologically. The LDS decided in the early 1900's during the administrations of Joseph F. Smith and Heber J. Grant to quietly repudiate the teachings of Brigham Young, John Taylor and Wilford Woodruff on one of the most essential Mormon doctrines - i.e. eternal marriage.
nbsp; Brigham Young taught that if the church gave up polygamy then they'd be damned. See Journal of Discourse, vol. 3, p. 266.
nbsp; Brigham Young, The only men who become Gods, even the Sons of Gods, are those who enter into polygamy. (Journal of Discourses 11:269).
nbsp; John Taylor, "Where did this commandment come from in relation to polygamy? It also came from God...When this commandment was given, it was so far religious, and so far binding upon the Elders of this Church that it was told them if they were not prepared to enter into it, and to stem the torrent of opposition that would come in consequence of it, the keys of the kingdom would be taken from them. When I see any of our people, men or women, opposing a principle of this kind, I have years ago set them down as on the high road to apostacy, and I do to-day; I consider them apostates, and not interested in this Church and kingdom" (Journal of Discourses 11:221).
nbsp; In 1886 John Taylor claimed a revelation and that there would eventually be a manifesto of apostates that the church would give up polygamy and that the one mighty and strong would set the house of the Lord in order. The mainline LDS church rejects this revelation.
