It signifies the assurance and joy that come from knowing God's promises and His steadfast love. This sound is not merely an audible noise but a profound spiritual reality that resonates with the hearts of the faithful.

2. Worship and Celebration: In the ancient Israelite context, the "joyful sound" would have been associated with the sounds of worship, including the blowing of trumpets, singing, and other expressions of praise during religious festivals and gatherings.
