{Suffer with it} (sunpaschei). Medical term in this sense
in Hippocrates and Galen. In N.T only here and  Ro 8:17  (of our
suffering with Christ). One of Solon's Laws allowed retaliation
by any one for another's injuries. Plato (_Republic_, V, 462)
says the body politic "feels the hurt" as the whole body feels a
hurt finger. {Rejoice with it} (sunchairei). This is
fortunately true also. One may tingle with joy all over the body
thanks to the wonderful nervous system and to the relation
between mind and matter. See  13:6  for joy of love with truth.
