'Silence' in the Bible

It stood still, but I couldn't discern its appearance. A form was before my eyes. Silence, then I heard a voice, saying,

"Men listened to me, waited, and kept silence for my counsel.

because I feared the great multitude, and the contempt of families terrified me, so that I kept silence, and didn't go out of the door --

"I will not keep silence concerning his limbs, nor his mighty strength, nor his goodly frame.
