This site's exposition
raise up offspring for your brother
on Genesis 38:8-10
Judah tells Onan to raise up offspring for his dead brother, the duty of a brother-in-law. That duty is levirate marriage, where a man fathers a son for his brother's widow and the first child counts as the dead brother's. Onan takes the wife and spills his seed on the ground so no offspring will be his brother's. The LORD puts him to death as well.
This site's exposition
the offspring would not belong to him
The Hebrew marks the act as repeated, each time he went in to her. A son counted to Er would inherit the firstborn's share of Judah's estate, and with Er's line empty that share would pass to Onan. He took the marriage and refused its purpose.
