'Mercy' in the Bible

For he says to Moses: "I will have mercy on whom I have mercy, and I will have compassion on whom I have compassion."

So then, it does not depend on human desire or exertion, but on God who shows mercy.

So then, God has mercy on whom he chooses to have mercy, and he hardens whom he chooses to harden.

And what if he is willing to make known the wealth of his glory on the objects of mercy that he has prepared beforehand for glory --

Just as you were formerly disobedient to God, but have now received mercy due to their disobedience,

so they too have now been disobedient in order that, by the mercy shown to you, they too may now receive mercy.

For God has consigned all people to disobedience so that he may show mercy to them all.

if it is exhortation, he must exhort; if it is contributing, he must do so with sincerity; if it is leadership, he must do so with diligence; if it is showing mercy, he must do so with cheerfulness.

and thus the Gentiles glorify God for his mercy. As it is written, "Because of this I will confess you among the Gentiles, and I will sing praises to your name."
