Psalms 135:1
1Praise the LORD! Praise the LORD’s name! Praise him, you servants of the LORD,
Praise him, you servants of the LORD. Clarke frames the whole as exhortation for goodness, greatness, wonders in nature and Egypt, then the vanity of idols. Servants are named as the choir, not as spectators.
Hallelujah is a sincere summons to willing praise under grace. The name is praised because it is worthy; servants answer freely, not as mute instruments.
Calvin: exhortation to praise for goodness to the chosen and for power apparent in the world. Servants and name come first so gratitude is not skipped for invented rites.
Praise reiterated because we undervalue it and are tardy. Praise the LORD; servants of the LORD.
