'Silent' in the Bible

it is told to the Gazathites, saying, 'Samson hath come in hither;' and they go round and lay wait for him all the night at the gate of the city, and keep themselves silent all the night, saying, 'Till the light of the morning -- then we have slain him.'

And they say, 'Rise, and we go up against them, for we have seen the land, and lo, very good; and ye are keeping silent! be not slothful to go -- to enter to possess the land.

and they say to him, 'Keep silent, lay thy hand on thy mouth, and go with us, and be to us for a father and for a priest: is it better thy being a priest to the house of one man, or thy being priest to a tribe and to a family in Israel?'
