'Bitterly' in the Bible

And Peter remembered the [prophetic] words of Jesus, when He had said, “Before a rooster crows, you will deny Me three times.” And he went outside and wept bitterly [in repentance].

And he went out and wept bitterly [deeply grieved and distressed].

And I began to weep greatly because no one was found worthy to open the scroll or look into it.
