A grand song of praise reaches its festive conclusion as David honors the arrival of the Ark of God at its permanent resting place [רד״ק, ביאור שטיינזלץ]. The celebration culminates in a powerful declaration of God's eternal nature, which is understood as lasting for all eternity [ביאור שטיינזלץ]. Others expand on this idea, explaining that the praise bridges two distinct realities, extending from this current world into the world to come [מצודת דוד].
As the singers finish their psalms, the gathered crowd responds by saying Amen [רד״ק]. This collective reply is a direct result of David's instruction, as he guides the people to actively confirm the spoken words and declare them to be the absolute truth [מצודת דוד]. Beyond this shared agreement, the people also add their own words of worship. Rather than a single uniform chant, each person expresses their gratitude and praise to God in their own unique way, matching their personal ability [מצודת דוד].
