It was told Saul that David was come to Keilah. Saul said, God has delivered him into my hand; for he is shut in, by entering into a town that has gates and bars.
"We have just witnessed how Saul, in an outburst of rage, became responsible for the destruction of the priestly city of Nob. In ch. 23, David, even while on the run from Saul, is shown saving a city from Philistine attack." [Note: Gordon, I & II Samuel . . ., p. 175.]
