There are 7427 blatant absurdities in the bible. Among them:
Different people have different opinions of what is vulgar or obscene. However, the following verses would likely be considered vulgar or obscene, were they in any setting other than the Bible.
She lusted after her lovers, whose genitals were like those of donkeys and whose semen was plentiful like that of horses.
Ezekiel 23: 20 For she doted upon their paramours, whose flesh is as the flesh of asses, and whose issue is like the issue of horses.
(This verse is also racist, referencing the Egyptian genitals.)
