King Solomon's probably in heaven unless he did something worse in hell.

God warned Solomon not to get involved with foreign women. This was his downfall, Hindi women, Persian women, Asiatic women,etc.

When a man has money, he can get any woman he wants.

But Solomon was not such a bad guy. He over-taxed the people, and he had many women. Plenty presidents overtaxed the people. But hell is a torture chamber. I don't think heinous crime and debilitating pain co-exist. In fact, the torture of hell was designed to burn out the desire for sin. Sin and fire don't coexist.

When fire's had its perfect work, sin is gone. So Solomon probably out-lasted hell fire, that when Jesus showed up, he was ready to go to heaven. And probably happy, too.
