サムエル記上 21:13

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.

and changeth his behaviour before their eyes, and feigneth himself mad in their hand, and scribbleth on the doors of the gate, and letteth down his spittle unto his beard.

So changing his behaviour before them, he made it seem as if he was off his head, hammering on the doors of the town, and letting the water from his mouth go down his chin.
