'Mercy' in the Bible

And they sang together by course in praising and giving thanks unto the LORD; because he is good, for his mercy endureth for ever toward Israel. And all the people shouted with a great shout, when they praised the LORD, because the foundation of the house of the LORD was laid.

And hath extended mercy unto me before the king, and his counsellers, and before all the king's mighty princes. And I was strengthened as the hand of the LORD my God was upon me, and I gathered together out of Israel chief men to go up with me.

For we were bondmen; yet our God hath not forsaken us in our bondage, but hath extended mercy unto us in the sight of the kings of Persia, to give us a reviving, to set up the house of our God, and to repair the desolations thereof, and to give us a wall in Judah and in Jerusalem.
