Trumpets: Were of a great variety of forms, and were made of divers materials.
Some were made of silver
(Numbers 10:2) and were used only by the priests
in announcing the approach of festivals and in giving signals of war.
Some were also made of rams' horns
(Joshua 6:8) They were blown at
special festivals, and to herald the arrival of special seasons
(Leviticus 23:24; 25:9; 1 Chronicles 15:24; 2 Chronicles 29:27; Psalms 81:3; 98:6) "Trumpets" are
among the symbols used in the Book of Revelation
(Revelation 1:10; 8:2)
