Joshua 8:18-23 meaning

Joshua 8:18-23 details the victory of Israel over Ai.

In the previous passage, Joshua gathered the Israelite soldiers and took them north of Ai to launch a full-frontal assault against Ai. While there, he instructed a second contingent of 5,000 men to set an ambush between Bethel and Ai. When the king of Ai saw the Israelite army, he took the bait and pursued them, not knowing there was an ambush west of Ai. The Israelites pretended to be beaten and fled before the adversaries, drawing them away from the city. All of Ai’s warriors followed Israel and failed to shut the city gates, allowing the ambush to unfold (Joshua 8:10-17).

In Joshua 8:18-23, the LORD intervenes to give Joshua further instructions concerning the battle. The Hebrew term translated as LORD is Yahweh, the true and eternal God who revealed Himself to Moses at the burning bush (Exodus 3:14). It often emphasizes God's covenant/treaty relationship with His people. Yahweh was responsible for Israel's victory. He was the great military Commander who led the Israelites, allowing them to conquer Ai. As such, He said to Joshua: Stretch out the javelin that is in your hand toward Ai (v. 18).

A javelin is a light spear thrown as a projectile weapon. In Joshua’s day, the javelin had a metal head attached to a short wooden shaft. God asked His emissary Joshua to raise it toward Ai and gave him the reason for doing so: For I will give it [Ai] into your hand. This statement reassured Joshua of the LORD's presence among Him and the Israelites.

Joshua trusted God and obeyed the divine word: He stretched out the javelin that was in his hand toward the city. This act served as a signal for the 5000 Israelite soldiers hiding west of Ai to begin their attack. Once the men in the ambush noticed that Joshua had pointed his spear, they rose quickly from their place (v. 19). Then, when he had stretched out his hand, they ran and entered the city. Having occupied Ai, the Israelite army captured it and quickly set it on fire.

Throughout the Bible, many battles end with the victors burning down the town of the defeated. In 586 BC, the Babylonians razed Jerusalem to the ground (2 Kings 25:9). During Israel's first conquest in Canaan, the people burned Jericho once Rahab and her family were in a safe place (Joshua 6:24). Similarly, "the sons of Judah fought against Jerusalem, captured it…and set it on fire" (Judges 1:8). In our passage, the Israelites burned Ai, destroying it just as they did to Jericho, per God's command (Joshua 8:1-2).

The destruction of Ai confused its soldiers. When they turned back and looked, behold, the smoke of the city ascended to the sky, and they had no place to flee this way or that (v. 20). At this point, the soldiers of Ai realized they were in a trap. Seeing the city in flames, they knew the Israelites were there. Therefore, they could not retreat, for the people [the Israelites who were stationed north of Ai] who had been fleeing to the wilderness turned against the pursuers.

We are given Joshua's perspective of the taking of the city, also: When Joshua and all Israel saw that the men in ambush had captured the city and that the smoke of the city ascended, they turned back and slew the men of Ai (v. 21). He saw that the plan had worked, that the city had been captured and set on fire; Joshua could see the smoke of the burning city which ascended into the sky. The Israelites in ambush west of Ai accomplished their task. Joshua then reversed the fake retreat and the Israelites made battle against their enemy to great success, having turned back, where they slew the men of Ai pursuing them.

The others [Israelite men] came out from the city to encounter them [the enemy] so that they were trapped in the midst of Israel, some on this side and some on that side (v. 22). In other words, the Israelite warriors surrounded their enemy. They slew them until no one was left of those who survived or escaped. Through God's intervention, the Israelites won the victory over Ai. They killed all the enemy soldiers but took alive the king of Ai and brought him to Joshua (v. 23). In the next section, we will learn that Joshua "hanged the king of Ai on a tree until evening" (Joshua 8:29).
