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.
Um, since adultery is a no no in the Ten Commandments, how do you reconcile Smith’s extensive practice of adultery?
Bet FastCoyote was not aware of what Martin Luther said!

Just WHO 'gave' them to Saul to begin with?
I see no mention of WIVES that were NOT Saul's being 'given' to him.

As your group used to do; before they chickened out.
It's not against YOUR law or history, either.
