1 Samuel 27:11

And David would leave neither man nor woman alive to bring news to Gath , thinking , lest they should tell about us and say , So David has done . Such was his custom all the while he lived in the country of the Philistines .

He did not leave a man or woman alive to be brought to Gath, for he thought, “They might inform on us and say, ‘This is what David did.`” And such was his practice as long as he lived in Philistine territory.

And David saved neither man nor woman alive, to bring tidings to Gath, saying, Lest they should tell on us, saying, So did David, and so will be his manner all the while he dwelleth in the country of the Philistines.
