Yet he was merciful; he forgave their iniquities and did not destroy them. Time after time he restrained his anger and did not stir up his full wrath.
NIV
But He, full of [merciful] compassion, forgave their iniquity and destroyed them not; yes, many a time He turned His anger away and did not stir up all His wrath and indignation.
AMP
