'Mercy' in the Bible

And they gave praise to the Lord, answering one another in their songs and saying, For he is good, for his mercy to Israel is eternal. And all the people gave a great cry of joy, when they gave praise to the Lord, because the base of the Lord's house was put in place.

And has given mercy to me before the king and his government and before all the king's great captains. And I was made strong by the hand of the Lord my God which was on me, and I got together out of Israel chief men to go up with me.

For we are servants; but our God has not been turned away from us in our prison, but has had mercy on us before the eyes of the kings of Persia, to give us new strength to put up again the house of our God and to make fair its waste places, and to give us a wall in Judah and Jerusalem.
