Charles H. Spurgeon on Psalms 148:12

Both young men, and maidens; old men, and children. Both sexes and all ages are summoned to the blessed service of song. Those who usually make merry together are to be devoutly joyful together: those who make up the ends of families, that is to say, the elders and the juveniles, should make the Lord their one and only end. Old men should by their experience teach children to praise; and children by their cheerfulness should excite old men to song. There is room for every voice at this concert: fruitful trees and maidens, cedars and young men, angels and children, old men and judges —all may unite in this oratorio. None, indeed, can be dispensed with: for perfect Psalmody we must have the whole universe aroused to worship, and all parts of creation must take their parts in devotion.
