Misericordia (mercy, compassion) sounds as much as misery laid to heart.
Christ’s heart sounded upon the sight and suit of these blind beggars, #Isa 63:15, and this was beyond all alms, should he have done no more for them. For when one gives an alms, he gives somewhat without himself, but by compassion we relieve another by somewhat within and from ourselves, while we draw out our soul (not our sheaf only) to the hungry, #Isa 58:10:
“and if you spend yourselves in behalf of the hungry
and satisfy the needs of the oppressed,
then your light will rise in the darkness,
and your night will become like the noonday.” (NIV)
