The answer is: 7

Josh 6:4

In the dramatic account of Jericho's fall, we see not just the number 7, but also a deeper pattern that resonates throughout biblical history. The Lord commanded that seven priests bear rams' horns ahead of the Ark of the Covenant as the Israelites circled the city. This ensemble of seven is not merely about quantity; it also symbolizes perfection and completeness in biblical numerology. It’s interesting to note that this resonates with other authoritative elements in Scripture—like the seven days of creation, where God rests on the seventh day, completing His work.

As they marched around Jericho each day, the priests’ rams' horns, known as shofars, conveyed messages of victory, worship, and the presence of God. Observers might find it captivating that shofars also played key roles during Jewish feasts and times of declaration, sounding calls to repentance and remembrance. This aligns beautifully with how the Israelites prepared for conquest with prayer and divine strategy rather than brute force alone.

When the final day arrived, the sound of those rams’ horns would resonate intensely—after six days of silence, the crescendo of shouts and blasts symbolized unity and faith. Marvelously, Jericho’s walls fell down not just as a physical event but also as a testament to collective belief and perseverance. Such stories reveal not just victories in ancient wars but lessons in faith that echo throughout journeys of communal hope and spirituality today.
