'Bitterly' in the Bible

But if you will not listen and obey,My soul will weep in secret for your pride;My eyes will weep bitterlyAnd flow with tears,Because the Lord’s flock has been taken captive.

Do not weep for the dead or mourn for him;But weep bitterly for the one who goes away [into exile],For he will never returnAnd see his native country [again].
