'Grief' in the Bible

that my grief is great and [there is] constant distress in my heart.

For grief according to [the will of] God brings about a repentance [leading] to salvation, not to be regretted, but worldly grief brings about death.

For indeed he was sick, coming near to death, but God had mercy on him and not [on] him only, but also [on] me, so that I would not have grief upon grief.
