Can a man have multi wives?KJV bible only please.?

Ok guys. I need some real serious answers on this one. I know God created Adam & Eve(one women) but Abraham, Isaac, and Jacob had multi wives. In Isaiah 4:1 it says in those days seven women shall cleave to one man (future tense). So if in those says 7 women shall have 1 man, then is it ok to have 7 wives today knowing tht this scripture is future tense( isnt this when war breaks out nd a lot of man ends up dieing? Also whats the purpose of multi wives? Ive heard its for income reasons but shouldn’t the man be the provider. I’ve heard some people say a man can have another wife if she’s bringing in extra income. Is this true? shouldnt the man being the 1 to provide for more than one wife. I need to see scriptures please. No scripts to backup then dnt reply..also the bible says (1Co_7:2 )to avoid fornication let every man have his own wife & let every wife have her own husband. So whats going on? Its like one script says its ok then I c something else. And if this is the case, y did our forefathers have multi wives & the kings. I mean there’s so much diseases going on. So the house has to be pledge because a man wants to lay with another woman who use to be a whore and decided to settle right after she got AIDs nd he didn’t know neither is first wife? also, what if a woman marries a man not knowing that he was a part if having multi wives, isnt that breaking the contract he had with his first wife when they've first got together? im pretty sure it wasnt, him his wife, stacey, Jonna etc..what if u got into the marriage without knowing about multi wives, then found out after u got married, can the first wife leave? i know marriage is a big thing in the KJV bible(only)and its not easy to get out once married. Example: if a man is in this truth nd his wife do not believe, he must remain with her. The only time he can divorce her or she divorce him is if they’ve committed adultery. Is the first wife trapped within the marriage of multi wives?Only from the KJV bible please reply.If its another version but close to the same sayings then let me know. some bible completely changes the meaning of a verse once translated. No Quran please!
