Therefore David ran, and stood upon the Philistine, and took his sword, and drew it out of its sheath, and slew him, and cut off his head there. And when the Philistines saw their champion was dead, they fled.

But our armor is Christ; it is that which the apostle Paul prescribes when, writing to the Ephesians, he says, “Take unto you the whole armor of God, that you may be able to withstand in the evil day;” and again, “Stand, therefore, having your loins gird about with truth, and having on the breastplate of righteousness; and your feet shod with the preparation of the gospel of peace; above all, taking the shield of faith, wherewith you shall be able to quench all the fiery darts of the wicked: and take the helmet of salvation, and the sword of the Spirit, which is the word of God.” Armed with these weapons, king David went forth in his day to battle. Taking from the torrent’s bed five smooth rounded stones, he proved that, even amidst all the eddying currents of the world, his feelings were free both from roughness and from defilement. Drinking of the brook by the way, and therefore lifted up in spirit, he cut off the head of Goliath, using the proud enemy’s own sword as the fittest instrument of death, smiting the profane boaster on the forehead and wounding him in the same place in which Uzziah was smitten with leprosy when he presumed to usurp the priestly office; the very place also in which shines the glory that makes the saints rejoice in the Lord, saying, “The light of your countenance is sealed upon us, O Lord.” Let us therefore also say, “My heart is fixed, O God, my heart is fixed: I will sing and give praise: awake up, my glory; awake, psaltery and harp; I myself will awake early”; that in us may be fulfilled that word, “Open thy mouth wide, and I will fill it”; and, “The Lord shall give the word with great power to them that publish it.” I am well assured that your prayer as well as mine is that in our contending, the victory may remain with the truth. For you seek Christ’s glory, not your own: if you are victorious, I also gain a victory if I discover my error.
