The OT seems full of such stories which are not very "family friendly".
No wonder Jonadav is not popular, even though the meaning is good. I guess Amnon is not popular either.
I seem to remember that Amnon was
Tamar's halfbrother and that her "full brother" Absalon had a revenge on Amnon later? Is Absalon popular?
A Scandinavian form of Absalon is
Axel and this name is popular here. But I doubt that anyone but a name nerd like me would know that
Axel is a form of the biblical Absalon.
