'Sound' in the Bible

It shall be, when you hear the sound of marching in the tops of the mulberry trees, that then you shall stir yourself up; for then Yahweh has gone out before you to strike the army of the Philistines."

So David and all the house of Israel brought up the ark of Yahweh with shouting, and with the sound of the trumpet.

But Absalom sent spies throughout all the tribes of Israel, saying, "As soon as you hear the sound of the trumpet, then you shall say, 'Absalom is king in Hebron!'"
