Joshua 11:6

‘ And YHWH said to Joshua, “Do not be afraid because of them, for tomorrow about this time I will deliver them up all slain before Israel. You shall hough their horses and burn their chariots with fire.” '

Joshua again sought the guidance of YHWH in the face of these powerful forces and YHWH assured him that he need fear nothing, for on the next day the whole force would be delivered into Joshua's hand. And this was so certain that He now gave instructions as to what to do with the horses and chariots after the battle. The hocks of the horses were to be cut rendering them useless for warfare, and the chariots were to be burned with fire. In consequence it would be a long time before they could be replaced and meanwhile the conquest of the land could take place satisfactorily. But Israel were not to try to make use of them (Isaiah 31:1; Psalms 20:7). They must trust in YHWH. These instructions, especially reference to the next day, suggests that Joshua had already brought his army across towards the enemy in a forced march.
