The walls of Jericho didn't just crumble; they collapsed in such a specific, miraculous way that it left no doubt about who was truly at work.
The Hebrew phrase translated 'fall down flat' (or 'under itself') suggests a complete, catastrophic collapse right where the wall stood, rather than just a section being breached. This wasn't a partial collapse that would still require a difficult scramble; it was an instantaneous leveling, creating a clear, unobstructed path for 'every man straight before him.' This detail is crucial. It wasn't the force of a shout or the vibration of a trumpet that brought the stone down; it was God's direct, precise intervention. This also accounts for Rahab's house, which was built into the wall, being preserved – a testament to divine discernment even amidst widespread judgment. It's a powerful reminder that when God acts, He does so with absolute authority and intentionality, often far beyond what human engineering or brute strength could achieve.
