“David said to Saul, 'Let no one lose heart on account of this Philistine; your servant will go and fight him.’ Saul replied, ‘You are not able to go out against this Philistine and fight him; you are only a young man, and he has been a warrior from his youth.’… ‘All those gathered here will know that it is not by sword or spear that the LORD saves; for the battle is the LORD’s, and he will give all of you into our hands.” -- 1 Samuel 17:32-33, 47
