Numbers 10:2-20

²“Make two trumpets out of hammered silver. They are to be used for summoning the Israelites and to have the camp move out.

³When both trumpets are blown, all the Israelites are to gather before you at the entrance to the Tent of Meeting.

⁴But if only one is blown, then only the tribal leaders are to gather before you.

⁵When you blow the trumpet loudly, which is the alarm signal to move out, the camps on the east side are to march out first.

⁶When you blow the trumpet loudly the second time, the camps on the south side are to march out. That's their signal to start moving.

⁷To summon the people, blow the trumpets normally, not the loud alarm signal.

⁸Aaron's descendants are to blow the trumpets. This regulation is for all time and for all future generations.

⁹When you're in your own land and have to go into battle against an enemy who has attacked you, blow the alarm signal and the Lord your God won't forget you—he will save you from your enemies.

¹⁰Blow the trumpets when you celebrate too, at your regular feasts and at the beginning of each month. This is when you give your burnt offerings and fellowship offerings which act as a reminder for you before your God. I am the Lord your God.”

¹¹The cloud rose up from the Tabernacle of the Testimony on the twentieth day of the second month of the second year.

¹²The Israelites left the Desert of Sinai and moved from place to place until the cloud stopped in the Desert of Paran.

¹³This was the first time they moved out following the Lord's command through Moses.

¹⁴The tribal divisions of Judah went first, marching out under their flag, with Nahshon, son of Amminadab, in charge.

¹⁵Nethanel, son of Zuar, was in charge of the tribal division of Issachar,

¹⁶and Eliab, son of Helon, was in charge of the tribal division of Zebulun.

¹⁷Then the Tabernacle was dismantled, and the Gershonites and the Merarites set off, carrying it.

¹⁸Then came the divisions of Reuben who marched out under their flag, with Elizur, son of Shedeur, in charge.

¹⁹Shelumiel, son of Zurishaddai, was in charge of the tribal division of Simeon,

²⁰and Eliasaph, son of Deuel, was in charge of the tribal division of Gad.
