[62] These kings which made war with, and were ready to fight the Gibeonites, being thus overthrown, Joshua returned again to the mountainous parts of Canaan; and when he had made a great slaughter of the people there, and took their prey, he came to the camp at Gilgal. And now there went a great fame abroad among the neighboring people of the courage of the Hebrews; and those that heard what a number of men were destroyed, were greatly aftrighted at it: so the kings that lived about Mount Libanus, who were Canaanites, and those Canaanites that dwelt in the plain country, with auxiliaries out of the land of the Philistines, pitched their camp at Beroth, a city of the Upper Galilee, not far from Cadesh, which is itself also a place in Galilee. Now the number of the whole army was three hundred thousand armed footmen, and ten thousand horsemen, and twenty thousand chariots; so that the multitude of the enemies aftrighted both Joshua himself and the Israelites; and they, instead of being full of hopes of good success, were superstitiously timorous, with the great terror with which they were stricken. Whereupon God upbraided them with the fear they were in, and asked them whether they desired a greater help than he could afford them; and promised them that they should overcome their enemies; and withal charged them to make their enemies' horses useless, and to burn their chariots. So Joshua became full of courage upon these promises of God, and went out suddenly against the enemies; and after five days' march he came upon them, and joined battle with them, and there was a terrible fight, and such a number were slain as could not be believed by those that heard it. He also went on in the pursuit a great way, and destroyed the entire army of the enemies, few only excepted, and all the kings fell in the battle; insomuch, that when there wanted men to be killed, Joshua slew their horses, and burnt their chariots and passed all over their country without opposition, no one daring to meet him in battle; but he still went on, taking their cities by siege, and again killing whatever he took.
