The Book of Joshua presents Jericho as the first city the Israelites conquer after crossing into Canaan, and the account gives its fall a distinctive, deliberately non-military shape: rather than a conventional siege or assault, priests carry the Ark of the Covenant around the city once daily for six days, accompanied by armed men marching in silence, and on the seventh day they circle it seven times while priests sound ram's horn trumpets, at which point the walls are described as collapsing outright and the city falls to the Israelites without a breach being fought for in any conventional sense.
The narrative's structure, obedience to a precise ritual sequence producing a military outcome no ordinary siege engine could achieve, sets a template the Book of Joshua returns to more than once in its account of the conquest, framing the Israelites' victories as products of covenant faithfulness rather than of tactical skill or superior numbers. Jericho's fall functions in the text as a foundational demonstration of that principle at the very outset of the conquest narrative, positioned to establish, before any other battle is recounted, that the campaign's outcomes were to be read as divinely directed rather than as ordinary military history.
