'Silence' in the Bible

All the multitude kept silence, and they listened to Barnabas and Paul reporting what signs and wonders God had done among the nations through them.

When he had given him permission, Paul, standing on the stairs, beckoned with his hand to the people. When there was a great silence, he spoke to them in the Hebrew language, saying,

For this is the will of God, that by well-doing you should put to silence the ignorance of foolish men:

When he opened the seventh seal, there was silence in heaven for about half an hour.
