Here are just two passages.......
Matthew 19:3-9
V.3 ¶ The Pharisees also came unto him, tempting him, and saying unto him, Is it lawful for a man to put away his wife for every cause?
V.4 And he answered and said unto them, Have ye not read, that he which made [them] at the beginning made them male and female,
V.5 And said, For this cause shall a man leave father and mother, and shall cleave to his wife: and they twain shall be one flesh?
V.6 Wherefore they are no more twain, but one flesh. What therefore God hath joined together, let not man put asunder.
V.7 They say unto him, Why did Moses then command to give a writing of divorcement, and to put her away?
V.8 He saith unto them, Moses because of the hardness of your hearts suffered you to put away your wives: but from the beginning it was not so.
V.9 And I say unto you, Whosoever shall put away his wife, except [it be] for fornication, and shall marry another, committeth adultery: and whoso marrieth her which is put away doth commit adultery.
1 Corinthians 7:1-2
V.1 ¶ Now concerning the things whereof ye wrote unto me: [It is] good for a man not to touch a woman.
V.2 Nevertheless, [to avoid] fornication, let every man have his own wife, and let every woman have her own husband.

The first marriage that God created was one man and one woman.
(This is God’s plan for marriage.)
Just because some men in the Bible had more than one wife, doesn’t make it right;
In fact this decision brought them much grief, because God didn’t bless it!
