1 Samuel 21:12-14

American Standard Version

¹² And David laid up these words in his heart, and was sore afraid of Achish the king of Gath. ¹³ And he changed his behavior before them, and feigned himself mad in their hands, and ^[a]scrabbled on the doors of the gate, and let his spittle fall down upon his beard. ¹⁴ Then said Achish unto his servants, Lo, ye see the man is mad; wherefore then have ye brought him to me?
