'Trumpet' in the Bible

When he had arrived, he blew a trumpet in the hill country of Ephraim; and the sons of Israel went down with him from the hill country, and he was in front of them.

So the Spirit of the Lord clothed Gideon [and empowered him]; and he blew a trumpet, and the Abiezrites were called together [as a militia] to follow him.

When I and all who are with me blow the trumpet (ram’s horn), then all around the camp you also blow the trumpets and shout, ‘For the Lord and for Gideon!’”
