The answer is: Held out his spear towards Ai

Josh 8:18 - Described as a javelin in some versions

In Joshua 8, we find a dramatic and pivotal moment in Israel's conquest of Canaan. As Joshua raised his spear — or javelin, depending on your translation — it was more than just a simple gesture; it was a signal charged with meaning. Picture the scene: the Israelite army, initially defeated by the city of Ai due to Achan's sin, is now making a bold strike for victory.

The moment he raised his hand was profoundly symbolic; it represented divine authority and guidance. Historically, warriors and leaders often raised their weapons as a rallying cry, inspiring trust and courage among their troops. Similarly, throughout Scripture, raised hands are seen as an expression of devotion and supplication to God, symbolizing reaching out for help and showing reliance on divine support.

Interestingly, Joshua's javelin gesture created a surprise tactic as it signaled an ambush. As the soldiers in ambush seized the moment, they charged and set the city ablaze, throwing the men of Ai into chaos. Think of the tactical brilliance here: the element of surprise is always a powerful weapon in warfare!

Echoes of this strategy resonate throughout Scripture; for instance, Gideon's men's torches and trumpets too caused tremendous confusion among the Midianites. In a culture that valued might and numbers, it's fascinating how God often turned conventional wisdom on its head. Truly, both seems to show that sometimes absolute victory lies in reliance on creative divine strategy rather than sheer force!
