The writings in the book of Psalms are amazing, for they emphasize the wonders of our God, and that we should praise and honor Him for His greatness.
When we read these psalms written by David and other writers, we see how they spoke about the Lord, His exploits and all the things He could do on the battlefields, as well as His beautiful creation, all so that we can be good managers of each of them.
4 Sing unto God, sing praises to his name: extol him that rideth upon the heavens by his name Jah, and rejoice before him.
5 A father of the fatherless, and a judge of the widows, is God in his holy habitation.
Psalm 68:4-5 (KJV)
