The answer is: 7

Josh 6:4

When Jericho's walls came tumbling down, it was more than just a display of brute force; it was a test of faith wrapped in a unique strategy curated by God Himself. You might think it unusual for priests to carry rams' horns, but this choice is steeped in symbolism! The number seven often signifies completion in the Bible—think of the Creation Week or Jericho's seventh day of silence before the shouts. It’s as if God is saying, "Trust in Me completely for what's coming."

Now, those rams' horns, or "shofars," have a rich history beyond Jericho. In ancient Israel, they were used throughout various religious ceremonies to announce significant events—like the Sabbath or Yuval, marking joyous occasions. Additionally, shofars play a vital role in alerting people, which ties it beautifully back to the moment leading to Jericho's demise.

Fun fact: These trumpets were named after the ram caught in a thicket by Abraham. It’s a compelling reminder of covenant and sacrifice, echoing throughout the Biblical narrative, culminating in God's plans for liberation and faithfulness. As those seven priests marched around Jericho, the sounds of hope must have rippled through the ranks of their desperate compatriots—a blaring wake-up call to remember ancient promises yet unfulfilled. So in their humble offices, the priests may have changed the course of history! Neat, huh?
