'Bitterly' in the Bible

Therefore I say, “Look away from me;Let me weep bitterly.Do not try to comfort me over the destruction of the daughter of my people.”

Now look, their brave men shout outside;The ambassadors [seeking a treaty] of peace weep bitterly.

and said, “Please, O Lord, just remember how I have walked before You in faithfulness and truth, and with a whole heart [absolutely devoted to You], and have done what is good in Your sight.” And Hezekiah wept greatly.
