'Bitterly' in the Bible

So I say: "Don't look at me! I am weeping bitterly. Don't try to console me concerning the destruction of my defenseless people."

Look, ambassadors cry out in the streets; messengers sent to make peace weep bitterly.

"Please, Lord. Remember how I have served you faithfully and with wholehearted devotion, and how I have carried out your will." Then Hezekiah wept bitterly.
