Use Scripture; ANY 'scripture', to show us SANCTION from the Lord.
Show me Sanctions in the OT for Abraham and Jacob and other in the various new dispensations the need to be replenished or populated the earth again under the Lord’s priesthood.
This shows that these ordinance have been removed from the scriptures because we know that Lord continue to work with his servants and did bless their posterity, we also know in Genesis that it was a commandment to replenished the earth.
The fact that the word “replenish” was used shows there was a population before!
Gen. 1: 28
28 And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth.
Gen. 9: 1
1 And God blessed Noah and his sons, and said unto them, Be fruitful, and multiply, and replenish the earth.
D&C 132: 63
63 But if one or either of the ten virgins, after she is espoused, shall be with another man, she has committed adultery, and shall be destroyed; for they are given unto him to multiply and replenish the earth, according to my commandment, and to fulfil the promise which was given by my Father before the foundation of the world, and for their exaltation in the eternal worlds, that they may bear the souls of men; for herein is the work of my Father continued, that he may be glorified.
Moses 2: 28
28 And I, God, blessed them, and said unto them: Be fruitful, and multiply, and replenish the earth, and subdue it, and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth.
Moses 5: 2
2 And Adam knew his wife, and she bare unto him sons and daughters, and they began to multiply and to replenish the earth.
Abr. 4: 28
28 And the Gods said: We will bless them. And the Gods said: We will cause them to be fruitful and multiply, and replenish the earth, and subdue it, and to have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth.
Um, try this. This is the Lord speaking to David though his prophet Nathan.
2 Samuel 12:8
And I gave thee thy master’s house, and thy master’s wives into thy bosom, and gave thee the house of Israel and of Judah; and if that had been too little, I would moreover have given unto thee such and such things.
Denying that the plurality of wives is a non biblical things is a hard thing to do. So many of the ancient prophets and fathers practiced it. We obviously don't practice it, but we do feel that it has been approved of the Lord(as referenced above) from time to time in order to create seed and a raise up nations unto the Lord.
Also, Martin Luther did not agree with you. Here is what he had to say on the matter.
"I confess that I cannot forbid a person to marry several wives, for it does not contradict the Scripture. If a man wishes to marry more than one wife he should be asked whether he is satisfied in his conscience that he may do so in accordance with the word of God. In such a case the civil authority has nothing to do in the matter." (De Wette II, 459, ibid., pp. 329-330.)
Ironically, many Jews today still practice it. It's not against their law or history.
