Shared ground
Psalm 150:5–6 closes the Psalter with a rising intensity. The text explicitly calls for praise with cymbals, using two sound-focused descriptions, and then broadens the summons to “everything that has breath.” The repeated “Praise him” keeps the target constant: Israel’s God (“Yah”).
The cymbals add a sense of maximum volume and public celebration. The final line shifts from instruments to living participants, using “breath” as the shared qualifier for joining the praise.
Where interpretation differs
Who is included in “everything that has breath.” Some read this as all living creatures (human and animal life) being included in the final summons. Others read it as a poetic way of saying “all people,” stressing universal human participation rather than a literal call for animals to praise.
What the two cymbal phrases mean. Some take them as two different instruments (or sizes/types) used together. Others take them as two ways of describing the same instrument’s sound (loud/resounding), emphasizing intensity rather than instrument variety.
How tied this is to temple worship. Some treat the language as mainly describing formal, organized worship settings with musicians. Others see the temple imagery as a launch point for a wider, any-place summons, especially because verse 6 widens the audience beyond the worship leaders.
Why the disagreement exists
The poem is compact and highly stylized. Its key terms (“everything,” “breath,” and the paired cymbal descriptions) can be read either as literal categories or as poetic ways of speaking. The text gives clear direction (praise with cymbals; all-with-breath praise Yah) while leaving the boundaries of “all” and the exact cymbal distinctions unstated.
What this passage clearly contributes
The passage ends the book by combining the loudest “how” (cymbals) with the widest “who” (everything with breath). Explicitly, it presents praise of Yah as fitting for vibrant, audible celebration and as a universal calling tied to life itself (“breath”), sealed with a final repeated “Praise Yah!”
