The great name on which David's faith rested, 'the Lord of hosts,' appears to have sprung into use in this epoch, and to have been one precious fruit of its frequent wars. Conflict is blessed if it teaches the knowledge of the unseen Commander who marshals not only men, but all the forces of the universe and the armies of heaven, for the defence of His servants and the victory of His own cause. The fulness of the divine name is learned by degrees, as our needs impress the various aspects of His character; and the revelation contained in this appellation is the gift of that fierce and stormy time, a possession for ever. He who defies the armies of Israel has to reckon with the Lord of these armies, whose name proclaims at once His eternal, self-originated, and self-sustained being, His covenant, His presence with His earthly host, and the infinite ranks of obedient creatures who are His soldiers and their allies. That is 'the Name' in the strength of which we may 'set up our banners' and be sure of victory. Note how David flings back Goliath's taunts in his teeth. He is sure that God will conquer through him, and, though he has no sword, that he will somehow hack the big head off; and that it is the host of the Philistines on whom the vultures and jackals are to feed to-day.
His faith sees the victory before the battle is begun, and trusts, not in his own weak power, but only 'in the name of the Lord.' Note, too, the result which he expects--no glory for himself, though that came unsought, when the shrill songs from the women of Israel met the victors, but to all the world the proof that Israel had a God, and to Israel ('this assembly') the renewed lesson of their true weapons and of their Almighty Helper. Such utter suppression of self is inseparable from trust in God, and without it no soldier of His has a right to expect victory. To fight 'in the name of the Lord' requires hiding our own name. If we are really going to war for Him, and in His strength, we ought to expect to conquer. Believe that you will be beaten, and you will be. Trust to Him to make you 'more than conquerors,' and the trust will bring about its own fulfilment.
IV. Observe the contrast in verse 48 between the slow movements of the heavy-armed Philistine and the quick run of the shepherd, whose 'feet were as hind's feet' (Psalm xviii. 33). Agility and confident alacrity were both expressed. His feet were shod with 'the preparedness of faith.' Observe, too, the impetuous brevity of the account in verse 49, of the actual fall of Goliath. The short clauses, coupled by a series of 'ands,' reproduce the swift succession of events, which ended the fight before it had begun; and one can almost hear the whiz of the stone as it crashes into the thick head, so strangely left unprotected by all the profusion of brass that clattered about him. The vulnerable heel of Achilles and the unarmed forehead of Goliath illustrate the truth, ever forgotten and needing to be repeated, that, after all precautions, some spot is bare, and that 'there is no armour against fate.'
The picture of the huge 'man-mountain' fallen upon his face to the earth, a huddled heap of useless mail, recalls the words of a psalm, 'When the wicked, even mine enemies and my foes, came upon me to eat up my flesh, they stumbled and fell' (Psalm xxvii. 2). Is it fanciful to hear in that triumphant chant an echo of Goliath's boast about giving his flesh to the fowls and the beasts, and a vision of the braggart as he tottered and lay prostrate? Observe, too, the contemptuous reiteration of 'the Philistine,' which occurs six times in the four verses (48-51). National feeling speaks in that. There is triumph in the sarcastic repetition of the dreaded name in such a connection. This was what one of the brood had got, and his fate was an omen of what would befall the rest. The champion of Israel, the soldier of God, standing over the dead Philistine, all whose brazen armour had been useless and his brazen insolence abased, and sawing off his head with his own sword, was a prophecy for the Israel of that day, and will be a symbol till the end of time of the true equipment, the true temper, and the certain victory, of all who, in the name of the Lord of hosts, go forth in their weakness against the giants of ignorance, vice, and sin. 'This is the victory that overcometh the world, even our faith.'
