Numbers 10:3-5

EasyEnglish Bible

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.
