Joshua 13:Now Joshua was old and stricken in years; and the Lord said unto him, Thou art old and stricken in years, and there remaineth yet very much land to be possessed. 7 Now therefore divide this land for an inheritance unto the nine tribes, and the half tribe of Manasseh
[Patriarchs & Prophets pp 510] The victory at Beth-horon was speedily followed by the conquest of southern Canaan. “Joshua smote all the country of the hills, and of the south, and of the vale.... And all these kings and their land did Joshua take at one time, because the Lord God of Israel fought for Israel. And Joshua returned, and all Israel with him, unto the camp at Gilgal.” The tribes of northern Palestine, terrified at the success which had attended the armies of Israel, now entered into a league against them. At the head of this confederacy was Jabin, king of Hazor, a territory to the west of Lake Merom.
“And they went out, they and all their hosts with them.” This army was much larger than any that the Israelites had before encountered in Canaan—“much people, even as the sand that is upon the seashore in multitude, with horses and chariots very many. And when all these kings were met together, they came and pitched together at the waters of Merom, to fight against Israel.” Again a message of encouragement was given to Joshua: “Be not afraid because of them: for tomorrow about this time will I deliver them up all slain before Israel.”
Near Lake Merom he fell upon the camp of the allies and utterly routed their forces. “The Lord delivered them into the hand of Israel, who smote them, and chased them ... until they left them none remaining.” The chariots and horses that had been the pride and boast of the Canaanites were not to be appropriated by Israel. At the command of God the chariots were burned, and the horses lamed, and thus rendered unfit for use in battle. The Israelites were not to put their trust in chariots or horses, but “in the name of the Lord their God.”
Psalms 33:16 There is no king saved by the multitude of an host: a mighty man is not delivered by much strength. 17 An horse is a vain thing for safety: neither shall he deliver any by his great strength. 18 Behold, the eye of the Lord is upon them that fear him, upon them that hope in his mercy.
May God add His blessing to the study of His word. "Good night" and God bless!
