18 Then God spoke to Joshua: "Stretch out the javelin in your hand toward Ai - I'm giving it to you." Joshua stretched out the javelin in his hand toward Ai.

Matthew Henry's Commentary on Joshua 8:18

Commentary on Joshua 8:3-22

(Read Joshua 8:3-22)

Observe Joshua's conduct and prudence. Those that would maintain their spiritual conflicts must not love their ease. Probably he went into the valley alone, to pray to God for a blessing, and he did not seek in vain. He never drew back till the work was done. Those that have stretched out their hands against their spiritual enemies, must never draw them back.
