Alex Frantz has a proposed Constitutional Amendment codifying marriage entirely on biblical principles.
1 Marriage in the United States shall consist of a union between one man and one or more women. Marriage shall not impede a man’s right to take concubines in addition to his wife or wives.
2 A marriage shall be considered valid only if the wife is a virgin. If the wife is not a virgin, she shall be executed. Marriage of a believer and a non-believer shall be forbidden.
3 Since marriage is for life, neither this Constitution nor the constitution of any State, nor state or federal law, shall be construed to permit divorce.
4 If a married man dies without children, his brother shall marry the widow. If he refuses to marry his brother’s 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.

It’s a mite Old Testament, but worth considering.
