'Forgave' in the Bible

My sin I acknowledged to you; my iniquity I did not hide. I said, "I will confess my transgressions to the LORD." And you forgave the guilt of my sin! Interlude

But he, being merciful, forgave their iniquity and didn't destroy them; He restrained his anger and didn't vent all his wrath.

LORD our God, you answered them; you were their God who forgave them, but also avenged their evil deeds.
