Psalms 149:4 - Joseph Benson’s Commentary on the Old and New Testaments

The Lord taketh pleasure in his people He loveth them above all people, and rejoiceth over them to do them good. He will beautify the meek The humble, and lowly, and contrite in heart, that tremble at his word, and submit to it; that are patient under their afflictions, and show all meekness toward all men. These the men of the world vilify and asperse; but God will justify them, and wipe off their reproach; nay, he will beautify, or adorn, or glorify them, as יפאר signifies. They shall appear, not only clear, but comely and honourable before all the world, with the comeliness and dignity wherewith he clothes them. He will beautify them with salvation, perhaps with temporal salvation, working remarkable deliverances for them; and then they who had lain among the pots, become as the wings of a dove covered with silver, Psalms 68:13: but especially with eternal salvation. The righteous shall be beautified indeed in that day when they shine forth as the sun in the kingdom of their Father.
