'Beatings' in the Bible

The blows of a wound will cleanse evil, as will beatings of the {innermost part}.

in beatings, in prisons, in disturbances, in troubles, in sleepless nights, in going hungry,

Are they servants of Christ?--I am speaking as though I were beside myself--I [am] more so, with far greater labors, with far more imprisonments, with beatings to a much greater degree, in [danger of] death many times.
