Joshua 8:18-28

18 And Jehovah said to Joshua, Stretch out the javelin that is in thy hand toward Ai; for I will give it into thy hand. And Joshua stretched out the javelin that he had in his hand toward the city.
19 And the ambush arose quickly from their place, and they ran when he stretched out his hand, and came into the city, and took it, and hasted and set the city on fire.
20 And the men of Ai turned and saw, and behold, the smoke of the city went up to heaven, and they had no power to flee this way or that way; and the people that fled to the wilderness turned upon the pursuers.
21 When Joshua and all Israel saw that the ambush had taken the city, and that the smoke of the city went up, they turned again, and slew the men of Ai.
22 And the others went out of the city against them; so they were in the midst of Israel, some on this side, and some on that side; and they smote them, until they let none of them escape or flee away.
23 And the king of Ai they took alive, and brought him to Joshua.
24 And it came to pass when Israel had ended slaying all the inhabitants of Ai in the field, in the wilderness wherein they had chased them, and they had all fallen by the edge of the sword, until they were consumed, that all Israel returned to Ai, and smote it with the edge of the sword.
25 And so it was, that all who fell that day, men as well as women, were twelve thousand, all the people of Ai.
26 And Joshua did not draw back his hand, which he had stretched out with the javelin, until they had utterly destroyed all the inhabitants of Ai.
27 Only, the cattle and the spoil of the city Israel took as prey to themselves, according to the word of Jehovah which he had commanded Joshua.
28 And Joshua burned Ai, and made it an everlasting heap of desolation to this day.

Joshua 8:18-28 Meaning and Commentary

INTRODUCTION TO JOSHUA 8

Joshua is encouraged to go up and take Ai, and is directed what method to make use of, Jos 8:1,2; accordingly he set an ambush on the west side of it, and, he and the rest of the army went up before it, Jos 8:3-13; which, when the king of Ai saw, he and all his forces came cut against them, and the Israelites making a feint as if they were beaten, drew on the men of Ai to pursue them, upon which the ambush arose and entered the city and set fire to it, Jos 8:14-19; the smoke of which being observed by Joshua and Israel, they turned back upon the pursuers, and the ambush sallying out of the city behind them, made an entire destruction of them, then slew all the inhabitants, took the spoil, burnt the city, and hanged the king of it, Jos 8:20-29; after this Joshua built an altar at Ebal, wrote the law on stones, and read the blessings and curses in it before all Israel, Jos 8:30-35.
