'Trumpet' in the Bible

"Speak to the {Israelites}, saying, 'In the seventh month, on [the] first [day] of the month, {you must have} a rest period, a remembrance of [the trumpet] blast, a holy assembly.

Then shalt thou cause the trumpet of the jubile to sound on the tenth day of the seventh month, in the day of atonement shall ye make the trumpet sound throughout all your land.
