Look LL, you have been given scriptures showing God’s plan for marriage is one man, one woman. You have seen scriptures showing the ravages of the sin of “adding wives,” and yet you can’t accept them. Is it because of your “new” scriptures like those found in the D&C?
Give me one Biblical scripture condemning slavery. Yes, I am changing the subject.
The subject NOW is, “if the Bible doesn’t outrightly condemn something, does that mean it is God’s commandment?”
The Bible describes what were probably monogamous marriages. The Bible also describes holy men — prophets and patriarchs — engaging in polygamous marriages without condemnation.
The Bible mentions slavery. The Bible does not, to my knowledge, describe holy men being slavemasters.
The Bible never says that Abraham having Hagar for a (second tier) wife was a sin. That is pure interpretation. The Bible never says that Israel having (at least) four wives was a sin. That is gloss placed on the Bible by others, whom you apparently agree with, as is your right.
