1 Samuel 21:13-15

21st Century King James Version

¹³ And he changed his behavior before them, and feigned himself mad in their hands, and 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. Why then have ye brought him to me?

¹⁵ Have I need of mad men, that ye have brought this fellow to play the madman in my presence? Shall this fellow come into my house?”
