Joshua 8:18

And the LORD said unto Joshua, Stretch out the spear that [is] in thy hand toward Ai; for I will give it into thine hand. And Joshua stretched out the spear that [he had] in his hand toward the city.

Ver. 18. Stretch out the spear.] Hastam vexillarem, the spear whereon hung the colours, for a sign to the soldiers, those of the ambush to enter, and those of the army to turn head against the enemy. By this means, saith one, as by Moses's rod, it pleased God to work for his people.
