The four highly dramatic Psalms 10, 11, 12 and 13 were King David's cries from the depth of his soul. He felt all alone. He couldn't understand why the evil people were succeeding on all sides and the righteous were downtrodden. His heart ached at the success of the tyrants at the expense of the meek and the helpless. He couldn't understand why Hashem seemed to be closing a blind eye to evil, crime and blasphemy. Then, when all seems lost, King David makes his comback. We can all relate to these four Psalms. Reciting them is a ticket to salvation.
