'Bitterly' in the Bible

Therefore I said, "Look away from me. I will weep bitterly. Don't labor to comfort me for the destruction of the daughter of my people.

Behold, their valiant ones cry outside; the ambassadors of peace weep bitterly.

and said, "Remember now, Yahweh, I beg you, how I have walked before you in truth and with a perfect heart, and have done that which is good in your sight." Hezekiah wept bitterly.

We roar all like bears, and moan bitterly like doves: we look for justice, but there is none; for salvation, but it is far off from us.
