'Mercy' in the Bible

Let your hearts be broken, and not your clothing, and come back to the Lord your God: for he is full of grace and pity, slow to be angry and great in mercy, ready to be turned from his purpose of punishment.

Let the priests, the servants of the Lord, be weeping between the covered way and the altar, and let them say, Have mercy on your people, O Lord, do not give up your heritage to shame, so that the nations become their rulers: why let them say among the peoples, Where is their God?
