And so it is shown in several places in the words of the Nevi’im that the main thing in saving a person’s life at a time of war, and in his overcoming his enemies, depends on how greatly the force of his bitachon in Hashem is strengthened at that time. As we find in the words of Yonasan the son of Shaul: he and his armor-bearer, by themselves, won the main part of the battle, and the opening of what he said about it to his armor-bearer was only in the middah of bitachon, as he said, “For nothing holds Hashem back from saving, with many or with few” (Shmuel I 14:6). And so we find (Shmuel I 30) with David: when he came to the city of Tziklag and found that it had been burned with fire, and their wives and their sons and their daughters had been taken captive, “and David and the people who were with him raised their voice and wept, until there was no strength left in them to weep” (Shmuel I 30:4), it is written afterward, in pasuk 6, “And David strengthened himself in Hashem his G-d.” And afterward it is written that he asked of the Urim VeTumim, and it answered him that he should go (Shmuel I 30:7–8); and so it was in the end: he recovered everything and defeated all his enemies, and struck them from dusk until the evening of the next day (Shmuel I 30:17). And this is why the pasuk wrote for us the asking of the Urim VeTumim after it is written, “And David strengthened himself in Hashem his G-d”: to teach us that the answer of the Urim VeTumim, that he should go, came only because he had first strengthened his bitachon in Hashem.
