Thought i should share to people like me who didn't know.

Genesis 38:8-10

Then Judah said to Onan, “Go in to your brother's wife and perform the duty of a brother-in-law to her, and raise up offspring for your brother.” But Onan knew that the offspring would not be his. So whenever he went in to his brother's wife he would waste the Fluid on the ground, so as not to give offspring to his brother. And what he did was wicked in the sight of the Lord, and he put him to death also.
