The Lord encourages Joshua, and promises to deliver Ai into his hands, and instructs him how he is to proceed against it, Jos 8:1, Jos 8:2. Joshua takes thirty thousand of his best troops, and gives them instructions concerning his intention of taking Ai by stratagem, Jos 8:3-8. The men dispose themselves according to these directions, Jos 8:9-13. The king of Ai attacks the Israelites, who, feigning to be beaten, fly before him, in consequence of which all the troops of Ai issue out, and pursue the Israelites, Jos 8:14-17. Joshua, at the command of God, stretches out his spear towards Ai, and then five thousand men that he had placed in ambush in the valley rise up, enter the city, and set it on fire, Jos 8:18, Jos 8:19. Then Joshua and his men turned against the men of Ai, and, at the same time, those who had taken the city sallied forth and attacked them in the rear; thus the men of Ai were defeated, their king taken prisoner, the city sacked, and twelve thousand persons slain, Jos 8:20-26. The Israelites take the spoils, and hang the king of Ai, Jos 8:27-29. Joshua builds an altar to God on Mount Ebal, and writes on it a copy of the law of Moses, Jos 8:30-32. The elders, officers, and judges, stand on each side of the ark, one half over against Mount Gerizim, and the other against Mount Ebal, and read all the blessings and curses of the law, according to the command of Moses, Jos 8:33-35.
