'Sound' in the Bible

Therefore when you do merciful deeds, don't sound a trumpet before yourself, as the hypocrites do in the synagogues and in the streets, that they may get glory from men. Most certainly I tell you, they have received their reward.

"The lamp of the body is the eye. If therefore your eye is sound, your whole body will be full of light.

He will send out his angels with a great sound of a trumpet, and they will gather together his chosen ones from the four winds, from one end of the sky to the other.
