I've been over this ground before with you -- at least 2-3 times.
Therefore, I will respond on the basis of "ALL"
All, Teppe thinks that just because his "D&C" scriptures mentions Isaac as a polygamist, that he was one...Yet the Bible says NOTHING at all about Isaac having more than a single wife!
Jacob became a polygamist because his father-in-law pulled one over on him; so he thinks what was introduced via deception is A-OK!
And as for Abraham, NOBODY called his wife's servant girl his "wife" except for his wife...before she slept with him.
For all we know that may have been one night; one week; one month.
Even his wife then referenced her as a "slave"...post pregnancy.
The angel of the Lord, post pregnancy, referenced her as the wife's servant...Abraham did, too...so did Moses...so did the apostle Paul in Galatians 4.
Abraham's NEXT wife came AFTER his first wife died.
A rational person wonders WHY the OTHER things in D&C tend to be IGNORED...
THE BOOK OF JACOB
THE BROTHER OF NEPHICHAPTER 224 Behold, David and Solomon truly had many wives and concubines, which thing was abominable before me, saith the Lord.
25 Wherefore, thus saith the Lord, I have led this people forth out of the land of Jerusalem, by the power of mine arm, that I might raise up unto me a righteous branch from the fruit of the loins of Joseph.
26 Wherefore, I the Lord God will not suffer that this people shall do like unto them of old.
27 Wherefore, my brethren, hear me, and hearken to the word of the Lord: For there shall not any man among you have save it be one wife; and concubines he shall have none;
28 For I, the Lord God, delight in the chastity of women. And whoredoms are an abomination before me; thus saith the Lord of Hosts.
29 Wherefore, this people shall keep my commandments, saith the Lord of Hosts, or cursed be the land for their sakes.
30 For if I will, saith the Lord of Hosts, raise up seed unto me, I will command my people; otherwise they shall hearken unto these things.
31 For behold, I, the Lord, have seen the sorrow, and heard the mourning of the daughters of my people in the land of Jerusalem, yea, and in all the lands of my people, because of the wickedness and abominations of their husbands.
32 And I will not suffer, saith the Lord of Hosts, that the cries of the fair daughters of this people, which I have led out of the land of Jerusalem, shall come up unto me against the men of my people, saith the Lord of Hosts.
