Joshua 8:20
And when the men of Ai looked behind them, they saw, and behold, the smoke of the city ascended vp to heauen, and they had no power to flee this way or that way: and the people that fled to the wildernesse, turned backe vpon the pursuers. Joshua 8:20 (KJV)
In this verse we are in the middle of the account in the book of Joshua describing the conquest of Ai by the Israelites. To understand its significance, let’s look at the surrounding events.
After the Israelites’ miraculous crossing of the Jordan River and the fall of Jericho, the LORD commanded Joshua to pursue the people of Ai (Joshua 7:2). Joshua gathered about three thousand men and attacked the city. The Israelites were unexpectedly defeated, and thirty‑36 of them were killed (Joshua 7:5).
Joshua, distressed by the loss, sought the Lord’s counsel. The Lord revealed that the defeat was caused by sin in the camp: Achan had taken some of the devoted‑to‑destruction spoils from Jericho and hidden them (Joshua 7:1‑21). To remove the breach, Achan, his family and their possessions were brought before the assembly, stoned to death, and the stolen items were burned publicly (Joshua 7:24‑26).
With the sin purged, the Lord instructed Joshua to take the whole army and capture Ai again. This time the Israelites followed the plan, set the city on fire, and the men of Ai, seeing the smoke rise, were caught between the pursuing Israelites and the burning city. Their lack of escape routes led to their defeat (Joshua 8:20).
The passage highlights God’s faithfulness in keeping His promise to Joshua after the people turned from disobedience. The smoke rising from Ai simply shows that the city was burning; it does not itself convey divine presence, though the victory was attributed to God’s help.
From a broader perspective, the account reminds readers of the importance of obedience and the consequences of sin. Achan’s disobedience brought defeat, but once the sin was dealt with, God’s favor and victory were restored. It underscores that actions have consequences and that repentance can lead to restoration.
In summary, Joshua 8:20 records the moment when the men of Ai saw their city ablaze, a turning point that led to their defeat. The episode stresses obedience, the impact of sin, and God’s faithfulness to those who return to Him.
