The Bible outlaws adultery, unnatural sex acts (such as homosexuality), prostitution, and other forms of perverted sex. God knew that these things could destroy Israel, just as they had destroyed other nations. They were crimes against morality—in other words, crimes challenging the God-given order for human society. God’s Law ruled out greed, lying, strange marriages, and anything else that would upset society. God expected His people to live morally upright lives. .
