The answer is: Trumpets|Trumpet

Joshua 6 - On the seventh day they walked round seven times and then sounded their trumpets causing the walls to fall down.

In the famous tale of Jericho, the priests wielded trumpets, the very instruments that signaled an extraordinary victory against fortified walls. What’s fascinating is the symbolism behind these trumpets—often linked with both battle and celebration. In biblical culture, the trumpet generally served as a divine alert, spurring both angels and humans to action.

Now, here’s something intriguing: the Hebrew word for trumpet, "shofar," originally referred to a ram's horn used in ancient ceremonies and rituals. One can imagine how its sound would waft through the desert air. This specific instance contributes to a chorus of echoes found throughout scripture where sounding trumpets aligned clear with divine instruction, from calling people to assembly to marking significant celebratory events (like during the Feast of Trumpets in Leviticus).

Day after day for six days, the Israelites marched around Jericho—an act uncovering layers of faith, patience, and obedience, better representing the spiritual weaponry compared to more conventional means. It culminated on the seventh day, a number brimming with holy prominence, reflecting perfection and completion. The mighty blast from the trumpets eventually signaled more than just the tumbling walls; it marked the triumph of spirit against formidable barriers, whispering to us all: sometimes, the strength of faith is the most powerful tool of all!
