***Same sex, yes, but multiple wives? Where in the Bible does it say it is an “abomination”?****
Deu 17:15 Thou shalt in any wise set [him] king over thee, whom the LORD thy God shall choose: [one] from among thy brethren shalt thou set king over thee: thou mayest not set a stranger over thee, which [is] not thy brother.
Deu 17:17 Neither shall he multiply wives to himself, that his heart turn not away: neither shall he greatly multiply to himself silver and gold.
Mat 19:9 And I say unto you, Whosoever shall put away his wife, except [it be] for fornication, and shall marry another, committeth adultery: and whoso marrieth her which is put away doth commit adultery.
So, according to this, taking a second wife is adultery.
And so many, including Old Testament people have done it.
