But when the people is to be gathered together, the sound of the trumpets shall be plain: and they shall not make a broken sound.
Blow ye the trumpet in Sion, sound an alarm in my holy mountain, let all the inhabitants of the land tremble: because the day of the Lord cometh, because it is nigh at hand,
And the sons of Aaron the priest shall sound the trumpets: and this shall be an ordinance for ever in your generations.
