John Chrysostom : If you don't mind, however, let us refer to a theme in our preaching earlier, so that by bringing the whole story to mind we may learn that nothing is stronger than the person protected by help from on high, and nothing is more vulnerable than the person deprived of this help, surrounded though he may be with countless armies. So this man David, quite young though he was and living in his father's house on account of his immaturity, heard the call of destiny for his virtue to become conspicuous; he was urged by his father to observe his brothers; he obeyed and was sent off to them. So, after coming on the scene to observe them, he saw the battle line drawn against the foreigner Goliath and the whole people of Saul's company withdrawing in fright and the king himself placed in particular danger. For a while he was happy to be an onlooker and went to see the strange and unusual sight of one person pitted against so many thousands. But his brothers could not tolerate the manliness of his bearing; they were moved to hatred and said to him, "Have you come for no other reason than to see the war." You haven't really come to observe us.Notice, however, his good sense and great restraint. Instead of saying anything rash to them, anything harsh, he extinguished the flame of their hatred; he mollified their hatred by saying, "Isn't it only a word?" I mean, surely you haven't observed me taking position in the ranks? I simply wanted to watch and find out the source of this man's extraordinary frenzy. "After all, who is this foreigner who reproaches the ranks of the living God?" Then, on hearing the man's awful arrogance and the unspeakable cowardice of those who had gone with Saul, he said, "What will be given to the man who cuts off his head?" He showed great boldness of spirit through these words and caused amazement in every one. Realizing this, Saul sent for the young man, who had experience of nothing other than shepherding, and when he saw his age he made fun of him. Then he learned from him how he dealt with bears when they raided his flocks; you see, this remarkable young man was obliged to describe this, not out of a wish to blow his own trumpet but because he had no choice if the king was to be inspired with courage and to have regard not for the poor impression he gave but for the faith concealed within him and the assistance from on high that made the young man stronger than the grown-ups, the unarmed stronger than the armed men, the shepherd than the soldiers. — HOMILIES ON Genesis 46.9-10
