Name Onan

Hebrew (אונן) means - "mourner, who is in mourning".

In the Book of Genesis Onan was the second son of Judah. According to the text, after God had killed Onan's older brother Er, Judah told Onan to have sexual intercourse with and impregnate Tamar, the widow of Er, so that the child or children could be declared to be Er's heir(s). Onan had sex with Tamar, but performed coitus interruptus each time, spilling his "seed" (semen) on the ground, so that there would not be any offspring which he could not claim as his own. The passage states that this displeased God, who killed Onan as punishment for disobedience.
