Saul "loved David greatly, and he became his 15 armor-bearer;" but the first trial of his humility and patience was not over, while many other trials were in store. After a while he was a second time sent back to his sheep; and though there was war with the Philistines, and his three eldest brethren 20 were in the army with Saul, and he had already essayed his strength in defending his father's flocks from wild beasts, and was "a mighty valiant man," yet he contentedly stayed at home as a private person, keeping his promise of 25 greatness to himself, till his father bade him go to his brethren to take them a present from him, and report how they fared. An accident, as it appeared to the world, brought him forward. On his arrival at the army, he heard the challenge of 30 the Philistine champion, Goliath of Gath. I need not relate how he was divinely urged to engage the giant, how he killed him, and how he was, in consequence, again raised to Saul's favor; who, with an infirmity not inconsistent with the 5 deranged state of his mind, seems to have altogether forgotten him. From this time began David's public life; but not yet the fulfillment of the promise made to him by Samuel. He had a second and severer trial 10 of patience to endure for many years; the trial of "being still" and doing nothing before God's time, though he had (apparently) the means in his hands of accomplishing the promise for himself. It was to this trial that Jeroboam afterwards 15 showed himself unequal. He, too, was promised a kingdom, but he was tempted to seize upon it in his own way, and so forfeited God's protection.
