תהלים, פרק קל״ב, פסוק ט״ז

A divine promise acts as a direct response to an earlier prayer, elevating the servants of the Temple to a higher physical and spiritual state. The initial request asked for the priests to be clothed in righteousness and for the pious to sing. In response, God promises an intensified, double reward of salvation and joy [מלבי״ם].

For the priests, God guarantees rescue from every trouble and obstacle [מאירי]. He presents this salvation through the metaphor of clothing to show that His protection will be public and obvious to all, just as a garment is clearly seen on a person's body [אבן עזרא]. Commentators offer different perspectives on how the priestly garments connect to this salvation. One approach suggests that the very act of wearing the honored priestly clothing brings about salvation and atonement [מצודת דוד, ביאור שטיינזלץ]. Looking toward the future, the mere wearing of these holy garments will be enough to bring salvation, completely replacing the need for sacrifices [אלשיך]. Another perspective views this as a direct exchange: because the priests put on their garments to serve God, He will clothe them with salvation as their reward [רד״ק].

The promise then turns to the pious ones, universally understood to be the Levites who sing in the Temple. They earn this title based on the blessing Moses gave to the tribe of Levi, where he referred to the tribe as God's pious man [רד״ק, אבן עזרא, מצודת דוד]. God promises that in return for the Levites singing to His name, He will provide them with such great abundance that their songs will naturally flow from a deep sense of inner gladness [רד״ק, מאירי]. This continuous singing reflects a massive, overwhelming joy [מלבי״ם]. Their song will serve as an expression of gratitude for the salvation they experience, and through the merit of this joyful singing, the Levites will earn the opportunity to sing once more over the vast goodness that will continue to flow to them [אלשיך].
