15 "If a man has two wives where one is loved but the other is unloved, and both of them bear him sons, but the firstborn is the son of the unloved wife, 16 then when he bequeaths his possessions to his sons, he must not give preference to the firstborn of the beloved wife over the firstborn of the unloved wife. 17 Instead, he must acknowledge the firstborn of the unloved wife by giving him double of everything he owns, because he is really the first fruit of his father's strength. The right of the firstborn belongs to him."
Bible verses about "polygamy" | ISV
5 "When two brothers are living together and one of them dies without leaving a son, his widow must not be married outside the family to a foreigner. Instead, the brother-in-law must go to her, take her as his wife, and by doing so perform the duty of a brother-in-law. 6 The firstborn whom she will bear will continue the name of the dead brother, so his name will not be erased from Israel. 7 But if the man does not want to marry his brother's widow, then she must go to the elders at the city gate and declare, 'My husband's brother refuses to perform the duty of a brother-in-law in order to preserve the name of his brother in Israel. He is not willing to perform the duty of a brother-in-law.' 8 Then the elders of the city are to summon him and speak with him. If he insists on saying, 'I don't want to marry her,' 9 then she is to approach her brother-in-law in the presence of the elders, remove his sandal, spit in his face, and say in response, 'May this be done to the man who does not preserve the lineage of his brother.' 10 Then his family name in Israel will be known 'as the family of the one whose sandal was removed.'"
