'Childless' in the Bible

As for a man who lies with his aunt, he has exposed his uncle's nakedness--they shall bear their sin; they shall die childless.

As for a man who marries his brother's wife, it [is] an abomination; he has exposed his brother's nakedness--they shall be childless.

And I will send {wild animals} out among you, and they shall make you childless, and they shall cut down your domestic animals, and they shall make you fewer; and your roads shall be desolate.
