'Blast' 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.

And you shall cause {a loud horn blast} to be heard on the seventh month on the tenth of the month; on the Day of Atonement you shall cause a ram's horn to be heard in all your land.
