Ram's Horn (יוֹבֵל, yobel', Jos 6:4,13; elsewhere "jubilee," "trumpet"). The Hebrew word keren, i.e. horn, is also used for the crooked trumpet, a very ancient instrument. Sometimes it was made of the horns of oxen, and sometimes ram's horns were employed. It is probable that in later times they were made of metal. They were employed in war, and on solemn occasions (Ex 19:13). The latter word is also rendered cornet (Da 3:5,7,10-15). SEE JUBILEE; SEE MUSICAL INSTRUMENTS.
