Ezekiel 33:3

"Set the trumpet to thy mouth. He shall come as an eagle against the house of the LORD, because they have transgressed my covenant, and trespassed against my law."

"In what place therefore ye hear the sound of the trumpet, resort ye thither unto us: our God shall fight for us."

"Cry aloud, spare not, lift up thy voice like a trumpet, and shew my people their transgression, and the house of Jacob their sins."

"Blow ye the trumpet in Zion, and sound an alarm in my holy mountain: let all the inhabitants of the land tremble: for the day of the LORD cometh, for it is nigh at hand;"

"For the builders, every one had his sword girded by his side, and so builded. And he that sounded the trumpet was by me."

"Declare ye in Judah, and publish in Jerusalem; and say, Blow ye the trumpet in the land: cry, gather together, and say, Assemble yourselves, and let us go into the defenced cities."

"O ye children of Benjamin, gather yourselves to flee out of the midst of Jerusalem, and blow the trumpet in Tekoa, and set up a sign of fire in Bethhaccerem: for evil appeareth out of the north, and great destruction."

"Set ye up a standard in the land, blow the trumpet among the nations, prepare the nations against her, call together against her the kingdoms of Ararat, Minni, and Ashchenaz; appoint a captain against her; cause the horses to come up as the rough caterpillers."
