1 Samuel 24:14-15

Finally, David makes a pathetic appeal to Saul, contrasting him in his grandeur as the king of Israel with the fugitive whom he so relentlessly persecuted. In calling himself a dead dog he implies that he was at once despicable and powerless. Even more insignificant is a flea , Hebrew, "one flea," "a single flea." The point is lost by omitting the numeral. David means that it is unworthy of a king to go forth with 3000 men to hunt a single flea. As the king's conduct is thus both unjust and foolish, David therefore appeals to Jehovah to be judge and plead his cause, i.e. be his advocate, and state the proofs of his innocence. For deliver me out of thy hand, the Hebrew is, "will judge me out of thy hand," i.e. will judge me, and by doing so justly will deliver me from thy power.
