9 "Then those who dwell in the cities of Israel will go out and set on fire and burn the weapons, both the shields and bucklers, the bows and arrows, the javelins and spears; and they will make fires with them for seven years.

Matthew Henry's Commentary on Ezekiel 39:9

Commentary on Ezekiel 39:1-10

(Read Ezekiel 39:1-10)

The Lord will make the most careless and hardened transgressors know his holy name, either by his righteous anger, or by the riches of his mercy and grace. The weapons formed against Zion shall not prosper. Though this prophecy is to be fulfilled in the latter days, it is certain. From the language used, it seems that the army of Gog will be destroyed by miracle.
