when was the shofar blown in the bible
Shofar The shofar was used to announce holidays[2] and the Jubilee year.[3] The first day of the seventh month (Tishrei) is termed "a memorial of blowing",[4] or "a day of blowing",[5] the shofar. They were used for signifying the start of a war.[6] Later, it was also employed in processions,[7] as musical accompaniment[8] and eventually it was inserted into the temple orchestra by David.[9] Note that the 'trumpets' described in Numbers 10 are a different instrument, described by the Hebrew word 'trumpet' (Hebrew: חצוצרה‎‎; ḥaṣoṣrah), not the word for shofar (Hebrew: שופר‎‎).
