How do you know that bible got crap ?
Here is one
DT 25
11 If two men are fighting and the wife of one of them
comes to rescue her husband from his assailant, and she reaches out
and seizes him by his private parts, 12 you shall cut off her hand.
Show her no pity.
So when u fight with another and your wife grab his ball, he can
cut her hand off 
DT25
5If brethren dwell together, and one of them die, and have
no child, the wife of the dead shall not marry without unto a
stranger: her husband's brother shall go in unto her, and take her
to him to wife, and perform the duty of an husband's brother unto
her.
So when your brother die, u can get your brother wife as your own
and have 2 wives. And women who r widowed canot re-marry.
