Genesis 38:9-10
King James Version (KJV)

⁹And Onan knew that the seed should not be his; and it came to pass, when he went in unto his brother's wife, that he spilled it on the ground, lest that he should give seed to his brother.

¹⁰And the thing which he did displeased the Lord: wherefore he slew him also.

Either way you read it, the Lord is kind of a dick. So Onan was supposed to knock up his brother's wife and when he decided he was killed. That is weird cult kind of shit.

according to the story, I don't think he was killed for not knocking up his brother's wife, I think was killed because he was supposed to try to get his brother's wife pregnant and he instead "pulled out".

Fixed.

I agree warbler, I think it was because he wasted his seed, but either way it's bad.
