The LORD is gracious, and full of compassion; slow to anger, and of great mercy.

The LORD is merciful and gracious, slow to anger, and plenteous in mercy.

Fire, water and government know nothing of mercy.

And thou shalt put the mercy seat upon the ark of the testimony in the most holy place.

Deserves it! I daresay he does. Many that live deserve death. And some that die deserve life. Can you give it to them? Then do not be too eager to deal out death in judgement. For even the very wise cannot see all ends.

He showed no pity. He showed no compassion. He showed no mercy. He deserves none for what he chose to do.
