Numbers 10:9-10

MLV(i) 9 And when you* go to war in your* land against the adversary that oppresses you*, then you* will shout out an alarm with the trumpets. And you* will be remembered before Jehovah your* God and you* will be saved from your* enemies. 10 Also in the day of your* gladness and in your* set feasts and in the beginnings of your* months, you* will blow the trumpets over your* burnt offerings and over the sacrifices of your* peace offerings. And they will be to you* for a memorial before your* God: I am Jehovah your* God.
