If a mans' wife is a woman that believes in every word of the Bible Proverbs 30:5 then this is not an issue. Exodus 21:10 ; Deuteronomy 21:15. The man is not under the control of the woman but the woman is to be under the control of the man. Read Genesis 3:16 and 1st Corinthians 11:1-3 this is the order set up by Jesus Christ. Finally read 1st Corinthians 7:10-15 If the wife doesn't want to believe that men can have more than one wife then they are the Anti-Christ. If they leave because of that and get the next man then they are committing adultery against the man,a sin. Read ST. Mark 10:12 Marriage in the Bible is sex/ the union between a man and a woman.
