1 Samuel 21:10-15 - David Flees To Achish In Gath
10 And David will rise and flee in that day from the face of Saul, and he will come to Achish, king of Gath. 11 And the servants of Achish will say to him, Is not this David king of the land? will they not answer to this in dances, saying, Saul struck against his thousands and David against his ten thousands?
12 And David will set these words in his heart, and he will be afraid greatly of the face of Achish, king of Gath. 13 And he will change his understanding in their eyes, and he will be foolish in their hand, and he will mark upon the doors of the gate, and his spittle will come down upon his beard.
14 And Achish will say to his servants, Behold, ye will see the man raving: wherefore will ye bring him to me? 15 Do I want mad men that ye brought this to rave to me? shall this come into my house?
