'Blast' in the Bible

"Tell the Israelis that on the first day of the seventh month you are to have a Sabbath of rest for you a memorial announced by a loud blast of trumpets. It is to be a sacred 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.
