To "thoughts that breathe and words that burn," like those of this song, David could not have given expression without having his whole soul stirred with the desire to repair the national disaster, and by God's help bring back prosperity and honour to Israel. Thus, both by the afflictions that saddened his heart and the stroke of prosperity that raised him to the throne, he was impelled to that course of action which is the best safeguard under God against the hurtful influences both of adversity and prosperity. Affliction might have driven him into his shell, to think only of his own comfort; prosperity might have swollen him with a sense of his importance, and tempted him to expect universal admiration;--both would have made him unfit to rule; by the grace of God he was preserved from both. He was induced to gird himself for a course of high exertion for the good of his country; the spirit of trust in God, after its long discipline, had a new field opened for its exercise; and the self-government acquired in the wilderness was to prove its usefulness in a higher sphere. Thus the providence of his heavenly Father was gradually unfolding His purposes concerning him; the clouds were clearing off his horizon; and the "all things" that once seemed to be "against him" were now plainly "working together for his good."
2 SAMUEL ii. 1-7.
The death of Saul did not end David's troubles, nor was it for a good many years that he became free to employ his whole energies for the good of the kingdom. It appears that his chastisement for his unbelieving spirit, and for the alliance with Achish to which it led, was not yet completed. The more remote consequences of that step were only beginning to emerge, and years elapsed before its evil influence ceased altogether to be felt. For in allying himself with Achish, and accompanying his army to the plain of Esdraelon, David had gone as near to the position of a traitor to his country as he could have gone without actually fighting against it. That he should have acted as he did is one of the greatest mysteries of his life; and the reason why it has not attracted more notice is simply because the worst consequences of it were averted by his dismissal from the Philistine army through the jealousy and suspicion of their lords. But for that step David must have been guilty of gross treachery either in one direction or another; either to his own countrymen, by fighting against them in the Philistine army; or to King Achish, by suddenly turning against him in the heat of the battle, and creating a diversion which might have given a new chance to his countrymen. In either case the proceeding would have been most reprehensible.
But to his own countrymen he would have made himself especially obnoxious if he had lent himself to Achish in the battle. Whether he contemplated treachery to Achish is a secret that seems never to have gone beyond his own bosom. All the appearances favoured the supposition that he would fight against his country, and we cannot wonder if, for a long time, this made him an object of distrust and suspicion. If we would understand how the men of Israel must have looked on him, we have only to fancy how we should have viewed a British soldier if, with a troop of his countrymen, he had followed Napoleon to the field of Waterloo, and had been sent away from the French army only through the suspicion of Napoleon's generals. In David's case, all his former achievements against the Philistines, all that injustice from Saul which had driven him in despair to Achish, his services against the Amalekites, his generous use of the spoil, as well as his high personal character, did not suffice to counteract the bad impression of his having followed Achish to battle. For after a great disaster the public mind is exasperated; it is eager to find a scapegoat on whom to throw the blame, and it is unmeasured in its denunciations of any one who can be plausibly assailed. Beyond all doubt, angry and perplexed as the nation was, David would come in for a large share of the blame; his alliance with Achish would be denounced with unmeasured bitterness; and, probably enough, he would have to bear the brunt of many a bitter calumny in addition, as if he had instigated Achish, and given him information which had helped him to conquer.
