'Have Mercy' in the Bible

Afterward," says the LORD, "I will deliver Zedekiah king of Judah, and his servants, and the people, even such as are left in this city from the pestilence, from the sword, and from the famine, into the hand of Nebuchadnezzar king of Babylon, and into the hand of their enemies, and into the hand of those who seek their life: and he shall strike them with the edge of the sword; he shall not spare them, neither have pity, nor have mercy."'

Is Ephraim my dear son? Is he a darling child? For as often as I speak against him, I do earnestly remember him still: therefore my heart yearns for him; I will surely have mercy on him," says the LORD.

then will I also cast away the seed of Jacob, and of David my servant, so that I will not take of his seed to be rulers over the seed of Abraham, Isaac, and Jacob: for I will cause their captivity to return, and will have mercy on them.'"

I will grant you mercy, that he may have mercy on you, and cause you to return to your own land.'
