The list of God-caused misfortunes is lengthy and found at Deuteronomy 28:15-68. Punishments include your wife being raped before you can consummate, eating your children, and being sold into slavery. I don't think any of that is very funny, except this one.
The LORD will smite thee with the botch of Egypt, and with the emerods, and with the scab, and with the itch, whereof thou canst not be healed. Deuteronomy 28:27I don't know what the botch is, but emerods are hemorrhoids! So, we better do what they say! Or, Jesus is going to infect us with itchy, scabby hemorrhoids that won't heal.
I find it interesting, though, that in the OT, we are threatened with real life, "on this earth" punishment. God wasn't threatening them with eternal torture after death. Also, the sins weren't "thought crimes". They were the breaking of taboos, like having sex with a woman on her period, or not burying your poo, or eating the wrong thing, or picking up sticks on the wrong day.
You know, if there really is a God and he is omnibenevolent, I don't think he'd have to resort to threats to get people to love him. Love doesn't work that way, anyhow!
