Both young men, and maidens - Those in the morning of life, just entering on their career; just forming their character: with ardor, elasticity, cheerfulness, hope; let them consecrate all this to God: let all that there is in the buoyancy of their feelings, in the melody of their voices, in their ardor and vigor, be employed in the praise and the service of God.
Old men, and children - Old men, with what remains of life, and children, with all that there is of joyousness - let all unite in praising God. Life, as it closes - life, as it begins - let it all be devoted to God.
Both young men, and maidens - Who are in the bloom of youth, and in the height of health and vigor; know that God is your Father; and let the morning and energy of your days be devoted to him.
Old men, and children - Very appropriately united here, as the beginning and conclusion of life present nearly the same passions, appetites, caprices, and infirmities: yet in both the beneficence, all-sustaining power, and goodness of God are seen.
Both young men, and maidens,.... These should praise the Lord, the one for their strength, the other for their beauty; and both should remember their Creator in the days of their youth, and fear, serve, and worship him; so they will praise and glorify him, as did Obadiah, Josiah, Timothy, and the four daughters of Philip the evangelist;
old men, and children; the former have had a large experience of the providential goodness of God, and, if good men, of the grace of God, and are under great obligation to praise the Lord for all that he has done for them; for they have known him that is from the beginning, and have seen many of his wonderful works, which they should not forget to declare to their children, to the honour and glory of God; and even out of the mouth of "children", of babes and sucklings, who have less knowledge, and less experience, God sometimes does ordain strength and perfect praise to himself; see Psalm 8:2; compared with Matthew 21:15.
