Author of The Book of Psalms

Author - David (According to Tradition). David went to many experiences in his life that he wrote about, especially when he was hunted down by King Saul from place to place like a Partridge in the wilderness. David was a young shepherd, he knew what it was like to tend his flock and to guard them from predators, this gave him a beautiful imagery for the Lord the great Shepherd. David was also a musician, a man of war, a king, a father, a husband, a friend, and many more. He repented over his sin in Psalm 51, acknowledging himself to be a sinner before God and God alone. God called David a man after my own heart and these experiences allowed him to share with the reader, a man who knew the heart of God. David was a master at finding different ways to praise God in life experiences and the book of Psalms is a wonder book for those who want to know how to please God. He was filled with the Holy Spirit (1 Samuel 16:13). There is no doubt the David wrote most of the Psalms, and the ones that he did not write are in his style as well.
