Lol, read what Jesus said in Mark 10:2-9.
Some Pharisees came up to Jesus, testing Him, and began to question Him whether it was lawful for a man to divorce a wife. And He answered and said to them, “What did Moses command you?” They said, “Moses permitted a man TO WRITE A CERTIFICATE OF DIVORCE AND SEND her AWAY.” But Jesus said to them, “ Because of your hardness of heart he wrote you this commandment. But from the beginning of creation, God MADE THEM MALE AND FEMALE. FOR THIS REASON A MAN SHALL LEAVE HIS FATHER AND MOTHER, AND THE TWO SHALL BECOME ONE FLESH; so they are no longer two, but one flesh. What therefore God has joined together, let no man separate.”
Jesus is quoting from Genesis in these verses. God made Adam and created one wife for him, Eve. Jesus says that God created them male and female (singular), not females.... And He said that the TWO become one flesh.
I'm always astonished on a Christian forum when a MAN says these kinds of things about polygamy. Don't ever hear women promoting polygeny, or polygamy, for that matter. All I can say to the idea of sharing my husband with another wife is YUCK!
