We associate the book of Psalm with Kind David. Not so; although, he wrote over half of them, Whoever compiled the book did us a favor by naming who wrote it at the beginning of most chapters, and often what it’s purpose was. Asaph is named on 12, Sons of Korah credited with 11 and Solomon with 2.
Psalm 23 is a favorite. It’s often memorized, and brings comfort to weary souls.
