'Trumpet' in the Bible

No hand shall touch him, but he shall surely be stoned or shot through; whether it is animal or man, he shall not live.' When the trumpet sounds long, they shall come up to the mountain."

It happened on the third day, when it was morning, that there were thunders and lightnings, and a thick cloud on the mountain, and the sound of an exceedingly loud trumpet; and all the people who were in the camp trembled.

When the sound of the trumpet grew louder and louder, Moses spoke, and God answered him by a voice.

All the people perceived the thunderings, the lightnings, the sound of the trumpet, and the mountain smoking. When the people saw it, they trembled, and stayed at a distance.
