I Samuel 21:13

13 Pelo que se contrafez diante deles, em cujas mãos se fingia doido, esgravatava nos postigos das portas e deixava correr saliva pela barba.

13 So he pretended to be insane in their presence; and while he was in their hands he acted like a madman, making marks on the doors of the gate and letting saliva run down his beard.
