Forasmuch then as Christ suffered for us in the flesh, arm yourselves also with the same mind; for he who has suffered in the flesh has ceased from sin;
Wuest -- The Greek word translated "arm yourselves" was used of a Greek soldier putting on his armor and taking his weapons. The noun of the same root was used of a heavy-armed foot-soldier who carried a pike and a large shield. The word was used of heavy-armed as against light-armed troops. Peter could have used the latter word. The Holy Spirit selected the former. The Christian needs the heaviest armor he can get, to withstand the attacks of the enemy of his soul.
