'Trumpet' in the Bible

And it came to pass, when he was come, that he blew a trumpet in the hill-country of Ephraim; and the children of Israel went down with him from the hill-country, and he before them.

But the Spirit of Jehovah came upon Gideon; and he blew a trumpet; and Abiezer was gathered together after him.

When I blow the trumpet, I and all that are with me, then blow ye the trumpets also on every side of all the camp, and say, For Jehovah and for Gideon.
