'Have Mercy' in the Bible

Then the Angel of the Lord said, “O Lord of hosts, how long will You withhold mercy and compassion from Jerusalem and the cities of Judah, against which You have had indignation and anger these seventy years [of the Babylonian captivity]?”

“I will strengthen the house of Judah [making it superior],And I will save the house of Joseph.I will bring them back [and allow them to live securely],Because I have had compassion on them.They will be as though I had not rejected them,For I am the Lord their God, and I will listen and answer them.
