Ψαλμών, or the Book of Psalms, is a collection of religious songs, prayers, and poems found in the Hebrew Bible and the Christian Old Testament. It consists of 150 individual psalms, attributed to various authors, including King David. The psalms express a wide range of emotions, from joy and praise to sorrow and repentance. The Book of Psalms serves as a vital part of worship in both Judaism and Christianity. Many psalms are recited or sung during religious services, and they are often used for personal reflection and meditation. The themes of faith, hope, and divine guidance resonate with believers across generations.
