דברי הימים א, פרק ט״ז, פסוק ל״ג

A time will come when absolute justice is revealed, bringing an overwhelming wave of joy that sweeps across all of creation. To capture the sheer scale of this happiness, a poetic picture of forest trees breaking into song is used to show how deeply joy will multiply across the earth [מצודת דוד]. Beyond mere poetry, this highlights a profound reality: even wild, untamed nature, which operates entirely outside of human control, will swell with emotion and gladness when God reveals Himself in His world [ביאור שטיינזלץ].

This universal celebration takes place as God arrives to judge the earth. Rather than a cause for fear, His judgment sparks immense joy. It marks the moment when God will finally grant every person the exact reward they deserve based on their actions [מצודת דוד].
