Commentators explain that the total destruction of Jericho, including its animals, was a direct command from God. This was not an act of plunder for Israel's enrichment. By destroying the livestock, which was a primary source of wealth, Israel demonstrated that they were acting as agents of divine judgment, not as conquerors seeking personal gain. The event is described as the 'vengeance of God' and a 'solemn sacrifice to God's justice.'
