According to the Psalmist, God always remembers and cares for people who have been hurt or treated badly, and He never ignores their cries for help. This means that God is like a loving parent who listens and takes care of those who are sad or in trouble.
Psalms 9:12: When he maketh inquisition for blood, he remembereth them: he forgetteth not the cry of the humble. [humble: or, afflicted]
This verse emphasizes the need to confess and forsake sins to obtain mercy, contrasting with Psalms 9:12 where God avenges blood and remembers the humble without mention of confession by wrongdoers.
Proverbs 28:13: He that covereth his sins shall not prosper: but whoso confesseth and forsaketh [them] shall have mercy.
