For  time immemorial, whenever Jews found themselves in difficult situations, whether individually or communally, they would open up the Book of Psalms and use King David's ageless poetic praises and supplications to beseech G‑d for mercy.

The Midrash tells us that when King David compiled the Psalms, he had in mind himself, as well as every Jew of every generation and every circumstance. No matter who you are and what the situation, the words of the Psalms speak the words of your heart and are heard On High. CHABAD
