Draft for a Constitutional Amendment for the U.S.A. to Defend Biblical Marriage:

• Marriage in the United States of America shall consist of a union
  between one man and one or more women. (Gen 29:17-28; II Sam 3:2-5.)
  
• Marriage shall not impede a man's right to take concubines in addition
  to his wife or wives. (II Sam 5:13; I Kings 11:3; II Chron 11:21)
  
• A marriage shall be considered valid only if the wife is a virgin. If
  the wife is not a virgin, she shall be executed. (Deut 22:13-21)
  
• Marriage of a believer and a non-believer shall be forbidden.(Gen 24:3;
  Num 25:1-9; Ezra 9:12; Neh 10:30, 2Cor 6:14)
  
• Since marriage is for life, neither the US Constitution nor any state
  law shall permit divorce. (Mark 10:9-12)
  
• If a married man dies without children, his brother must marry the
  widow. If the brother refuses to marry the widow, or deliberately does not
  give her children, he shall pay a fine of one shoe and be otherwise
  punished in a manner to be determined by law.(Gen. 38:6-10; Deut 25:5-10)
  
• In lieu of marriage (if there are no acceptable men to be found), a
  woman shall get her father-in-law drunk and have sex with him. (Gen 19:31-36)
