“Seven priests with rams' horns”
Have seven priests carry seven rams' horns in front of the ark. Then on the seventh day, march around the city seven times, while the priests blow the horns. (Joshua 6:4 BSB)
What it sounds like today
Soldiers blowing trumpets as some kind of sonic weapon.
The cultural key
The instruments and the sevens turn the conquest of Jericho into an act of worship rather than warfare. The 'trumpets' are shofars, curved ram's-horn instruments blown in Israel's worship and to signal sacred events, not the straight silver signal-trumpets, and certainly not weapons. Seven priests carry seven shofars in front of the ark of the covenant (God's throne-symbol), and for seven days the army marches around the city, seven times on the seventh day, before a single shout brings the walls down. The relentless sevens (the number of completeness and of the sabbath) and the priestly, ark-led procession frame the whole event as a liturgy: Israel does not besiege Jericho with rams and towers; it processes around it in worship, and God gives the city. The point is that the victory is God's gift, received by obedience and worship, not won by military might. A modern reader imagines a sonic weapon; the first hearers saw a sacred procession that toppled a fortress.
Recovered meaning
The Jericho 'trumpets' are worship shofars carried by priests around the ark, not weapons; the sevenfold, seven-day procession makes the city's fall a liturgy. Jericho is taken by worship and obedience, not by siege, and the victory is God's gift.
