1 Samuel 21:10

7 And there is a man of the servants of Saul on that day detained before Jehovah, and his name is Doeg the Edomite, chief of the shepherds whom Saul hath.

8 And David saith to Ahimelech, `And is there not here under thy hand spear or sword? for neither my sword nor my vessels have I taken in my hand, for the matter of the king was urgent.'

9 And the priest saith, `The sword of Goliath the Philistine, whom thou didst smite in the valley of Elah, lo, it is wrapped in a garment behind the ephod, if it thou dost take to thyself, take; for there is none other save it in this place.' And David saith, `There is none like it--give it to me.'

10 And David riseth and fleeth on that day from the face of Saul, and cometh in unto Achish king of Gath;

11 and the servants of Achish say unto him, `Is not this David king of the land? is it not of this one they sing in dances, saying, `Saul smote among his thousands, and David among his myriads?'

12 And David layeth these words in his heart, and is exceedingly afraid of the face of Achish king of Gath,

13 and changeth his behaviour before their eyes, and feigneth himself mad in their hand, and scribbleth on the doors of the gate, and letteth down his spittle unto his beard.
