Numbers 10:4-6

Expanded Bible

⁴ If you blow only one trumpet, the leaders, the heads of the ·family groups [clans] of Israel, should meet before you. ⁵ When you loudly blow the trumpets, the ·tribes [^Lcamps] camping on the east should move. ⁶ When you loudly blow them again, the ·tribes [^Lcamps] camping on the south should move; the loud sound will tell them to move.
