Numbers 10:3-15

³And when they shall blow with both, all the congregation shall assemble themselves unto thee at the door of the tabernacle of the congregation.

⁴And if they blow with but one, then shall assemble themselves unto thee the princes, the heads of the thousands of Israel.

⁵And when ye blow an alarm, then shall set forward the camps that encamp on the east side.

⁶And when ye blow an alarm the second time, then shall set forward the camps that encamp on the south side: an alarm shall they blow for their setting forward.

⁷But at the assembling of the assembly, ye shall blow, but ye shall not sound an alarm.

⁸And the sons of Aaron, the priests, shall blow with the trumpets; and they shall be to you for an ordinance for ever throughout your generations.

⁹And if ye go to war in your land against the oppressor that oppresseth you, then shall ye blow an alarm with the trumpets; and ye shall be remembered before the Lord your God, and ye shall be saved from your enemies.

¹⁰And on the day of your gladness, and on your appointed festivals, and on the beginnings of your months, shall ye blow with the trumpets over your burnt-offerings, and over the sacrifices of your peace-offerings; and they shall be to you for a memorial before your God: I am the Lord your God.

¹¹And it came to pass in the second year, in the second month, on the twentieth day of the month, that the cloud was taken up from off the tabernacle of the testimony.

¹²And the children of Israel set forward on their journeys from the wilderness of Sinai, and the cloud halted in the wilderness of Paran.

¹³And they set forward for the first time at the order of the Lord by the hand of Moses.

¹⁴And the standard of the camp of the children of Judah set forward at the first, according to their armies: and over their host was Nachshon the son of 'Amminadab.

¹⁵And over the host of the tribe of the children of Issachar was Nethanel the son of Zuar.
