Numbers 10:6-8

EasyEnglish Bible

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.
