1 Samuel 21:13

Maka di hadapan mereka, Daud mengubah tingkah lakunya dengan berpura-pura menjadi gila. Dia menggores-gores pintu gerbang dan membiarkan air liurnya menetes ke jenggotnya.

And he changed his behaviour 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.
