Nevertheless we made our prayer to our God, and set a watch against them day and night, because of them.
A believer's watchfulness is like that of a soldier. A sentinel posted on the walls, when he discerns a hostile party advancing, does not attempt to make head against them himself, but informs his commanding officer of the enemy's approach, and leaves him to take the proper measures against the foe. So the Christian does not attempt to fight temptations in his own strength: his watchfulness lies in observing its approach, and in telling God of it by prayer.
