Hosea was commanded by God to take an adulteress as his wife. Hosea got married to his new wife. They have a couple of kids together, and then she left him and returned to her adulterous life. Either she became a prostitute, or she acted as if she was one. [...]
In fact, she went as far as to make herself a sex slave of another. The Scriptures said that God instructed Hosea to seek her out, and to buy her back, bring her home and love her as his wife.
I read somewhere (back in Sunday school) that they use to stone people who engaged in that behavior. Oh well, it's good to see that people believe in a God of grace--as we all have probably committed a few mistakes here or there in our lifetime.
