'Have Mercy' in the Bible

Therefore the LORD will wait, that he may be gracious to you; and therefore he will be exalted, that he may have mercy on you, for the LORD is a God of justice. Blessed are all those who wait for him.

In overflowing wrath I hid my face from you for a moment; but with everlasting loving kindness will I have mercy on you," says the LORD your Redeemer.

let the wicked forsake his way, and the unrighteous man his thoughts; and let him return to the LORD, and he will have mercy on him; and to our God, for he will abundantly pardon.
