And David inquired of the LORD, saying, Shall I go up against the Philistines? will you deliver them into my hand? And the LORD said unto David,
Go up: for I will doubtless deliver the Philistines into your hand.

Ambrose of Milan
AD 397
After that [the killing of Goliath] he never entered on a war without seeking counsel of the Lord. Thus he was victorious in all wars, and even to his last years [he] was ready to fight. And when war arose with the Philistines, he joined battle with their fierce troops, being desirous of winning renown, while careless of his own safety. But this is not the only kind of fortitude which is worthy of note. We consider their fortitude glorious, who, with greatness of mind, “through faith stopped the mouth of lions, quenched the violence of fire, escaped the edge of the sword, out of weakness were made strong,” They did not gain a victory in common with many, surrounded by comrades and aided by the legions, but [they] won their triumph alone over their treacherous foes by the mere courage of their own souls. - "Duties of the Clergy 1.35.177"
