Psalms 148:11

11.Kings of the earth, etc. He now turns his address to men, with a respect to whom it was that he called for a declaration of God’s praises from creatures, both above and from beneath. As kings and princes are blinded by the dazzling influence of their station, so as to think the world was made for them, and to despise God in the pride of their hearts, he particularly calls them to this duty; and, by mentioning them first, he reproves their ingratitude in withholding their tribute of praise when they are under greater obligations than others. As all men originally stand upon a level as to condition, the higher persons have risen, and the nearer they have been brought to God, the more sacredly are they bound to proclaim his goodness. The more intolerable is the wickedness of kings and princes who claim exemption from the common rule, when they ought rather to inculcate it upon others and lead the way. He could have addressed his exhortation at once summarily to all men, as indeed he mentions peoples in general terms; but by thrice specifying princes he suggests that they are slow to discharge the duty, and need to be urged do it. Then follows a division according to age and sex, to show that all without exception are created for this end, and should unitedly devote their energies to it. As to old men, the more God has lengthened out their lives the more should they be exercised in singing his praises; but he joins young men with them, for though they have less experience from continued habit, it will be inexcusable if they do not acknowledge the great mercy of God in the vigor of their lives. In speaking of girls or virgins, the particle גם, gam, also, is not merely expletive, but added to make the words more emphatical, conveying the truth that even the young women who are not so liberally educated as the male sex, being considered as born for domestic offices, will omit their duty if they do not join with the rest of the Church in praising God. It follows that all from the least to the greatest are bound by this common rule.
