Psalm 148 commands everything in creation to praise Yahweh:
— “the heavens” :1
— “angels” :2
— “sun and moon … stars of light” :3
— “the earth” :7
— “sea monsters” :7
— “fire and hail, snow and clouds” :8
— “mountains and all hills; fruit trees and all cedars” :9
— “beasts and all cattle” :10
— “kings of the earth and all peoples; princes and judges of the earth; both young men and virgins, old men and children” :11-12
In other words, EVERYONE, and every THING is to praise the Lord. This also points to the PURPOSE of everything; everything which exists, exists to praise God.
