Numbers 10:1-10
The silver trumpets
1 The Lord said to Moses, 2 ‘Make two trumpets from one piece of silver. Use a hammer to make them in the right shape. Make a noise with them to tell the people that they must come together. Also, use the trumpets to tell the people that they must move the camp. 3 When the people hear the sound from both trumpets, all the people must meet you. They must meet you at the door of the Tent of Meeting. 4 But you may want only the leaders of Israel's tribes to meet you. If you want that, a priest should make the sound from only one trumpet. 5 But when the sound is one short sound, the tribes on the east side of the camp must start to travel. 6 When they hear the next short sound, the tribes on the south side of the camp must start to travel. Short sounds from the trumpet will tell the people that they must start to travel. 7 But when you want everyone to meet together, make a different sound with the trumpet.
8 The priests, the sons of Aaron, must use the trumpets to make a noise. This is a rule for you and for all your descendants. 9 Use the trumpets to tell everyone when an enemy is attacking you in your own land. Make a sound with the trumpets to tell the people that they must fight the enemy. Then the Lord your God will hear and he will save you from your enemies. 10 You must make sounds with the trumpets on your happy days, too. And you must make sounds with the trumpets at your regular festivals and on the first days of your months. And you must make sounds with the trumpets over your burnt offerings, and over your friendship offerings. God will hear and he will remember you. I am the Lord your God.’
