Psalms he wrote as a boy

Some other Psalms he wrote as a young boy in the fields while he watched his father's flocks: Psalm 23 (the most famous psalm)-- I'll bet he was only 12 or 13 years old when he "wrote" it, some of psalm 2, psalm 8, and some of psalm 139, psalm 19, psalm 29.

For each descriptive word about God that David grazed upon in his psalms, he probably had a wealth of knowledge to describe. For instance, when David spoke of God’s justice or faithfulness, he was only listing the table of contents of all the he could say about God. He probably had so many things to say about the different attributes of God. Ps 36 he only references them.
