To throw oneself on the mercy of the court.
A mercy he wasn't killed.
A heart full of mercy.
It was a mercy that no one was hurt.
Taking in the refugees was an act of mercy.
An example of mercy is giving someone a lighter punishment than they deserve.
Psalms 40:11 Do not withhold Your tender mercies from me, O Lord.
It was a mercy that we were not inside when the roof collapsed.
