As someone in the comments pointed out, the Onan bit is often taught as the Biblical prohibition against ************* Or, as Monty Python said, "Every sperm is sacred".
I could probably come up with at least another half-dozen verses like the ones listed. I've already quoted a couple times before the passage from Lamentations in which mothers are forced to cook and eat their own children. On the topic of circumcision, there's a good bit where one of the Biblical leaders (Joshua maybe?) tells a city that they may be spared if they agree to be circumsized as the Lord commands. They comply and, the next day while they are all still in pain, the leader goes in and kills them all.
Crap, now I need to look it up.
