'Mercy' in the Bible

And he made prayer to the Lord and said, O Lord, is this not what I said when I was still in my country? This is why I took care to go in flight to Tarshish: for I was certain that you were a loving God, full of pity, slow to be angry and great in mercy, and ready to be turned from your purpose of evil.

And am I not to have mercy on Nineveh, that great town, in which there are more than a hundred and twenty thousand persons without the power of judging between right and left, as well as much cattle?
