Why did the Israelites burn Jericho after capturing it?

The Israelites burned Jericho after capturing it as an act of total destruction commanded by God, symbolizing the complete eradication of the city's wickedness and idolatry. This act served to demonstrate their obedience to divine instructions, as outlined in the biblical narrative of Joshua. The burning also ensured that the city would not be rebuilt or repopulated, reinforcing the idea of divine judgment against its inhabitants. Additionally, it marked a significant victory and established the Israelites' presence in the Promised Land.
