Jesus reject multiple marriage:
John 4:17-18
The woman answered and said to him, “I do not have a husband.” Jesus answered her, “You are right in saying, ‘I do not have a husband.’ For you have had five husbands, and the one you have now is not your husband. What you have said is true.”
and that’s the best you can do? a passage referring to serial monogamy? He said “you have HAD five husbands”.. the woman had been married multiple times.. not to multiple men at once.. I love people who take things out of context..
It was the Romans who put an end to polygyny in order to control the people.. do your homework next time.
