Is polygamy OK?
Yes, the Bible approves of polygamy
There are many polygamists in the Bible. Some of them were God's favorite people (including Abraham, Jacob, Gideon, Solomon, and David). God didn't seem to mind.And Lamech took unto him two wives. Genesis 4:19God even gave David Saul's wives. (He wouldn't do that if polygamy.he didn't approve of polygamy.)
No, the Bible disapproves of polygamy
God created only one woman to be Adam's help meet. This seems to imply that God intended marriage to involve one man and one woman.The LORD God caused a deep sleep to fall upon Adam, and he slept: and he took one of his ribs, and closed up the flesh instead thereof; And the rib, which the LORD God had taken from man, made he a woman, and brought her unto the man. And Adam said, This is now bone of my bones, and flesh of my flesh: she shall be called Woman, because she was taken out of Man.Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh. Genesis 2:21-24Jesus seems to agree with this passage, saying that a man and a woman become "one flesh" in marrige, as it was in "the begining."Have ye not read, that he which made them at the beginning made them male and female, And said, For this cause shall a man leave father and mother, and shall cleave to his wife: and they twain shall be one flesh? Wherefore they are no more twain, but one flesh. Matthew 19:4-5And although it's OK for a king to have more than one wife, he shouldn't have too many. (Although how many is too many is not specified.)Neither shall he [the king] multiply wives to himself. Deuteronomy 17:17Paul seemed to think that a marriage should only be between one man and one woman.Let every man have his own wife, and let every woman have her own husband. 1 Corinthians 7:2As did the author of Ephesians.Let every one of you in particular so love his wife even as himself; and the wife see that she reverence her husband. Ephesians 5:33
Polygamy is OK, unless you're a bishop
A bishop then must be blameless, the husband of one wife.... 1 Timothy 3:2
