Numbers 10:4-6

Evangelical Heritage Version

⁴ If they blow just one trumpet, then the tribal chiefs, the heads of the Israelite clans, will gather to you.

⁵ When you blow the signal on the trumpets, the camps that are on the east side will set out. ⁶ When you blow the signal a second time, the camps that are on the south side will set out. This will be the signal to set out.
