Yahweh said to Joshua, Don't fear them: for I have delivered them into your hands; there shall not a man of them stand before you.
It is moreover worthy of notice that Joshua did not abuse the divine promise by making it an excuse for sluggishness, but felt the more vehemently inflamed after he was assured of a happy issue. Many, while they ostentatiously express their faith, become lazy and slothful from perverse security. Joshua hears that victory is in his hand, and that he may gain it, runs swiftly to battle. For he knew that the happy issue was revealed, not for the purpose of slackening his pace or making him more remiss, but of making him exert himself with greater zeal. Hence it was that he took the enemy by surprise.
