Numbers Chapter 10 Verse 9And if ye go to war in your land against the enemy that oppresseth you, then ye shall blow an alarm with the trumpets; and ye shall be remembered before the LORD your God, and ye shall be saved from your enemies.

Or [whether it were] two days, or a month, or a year, that the cloud tarried upon the tabernacle, remaining thereon, the children of Israel abode in their tents, and journeyed not: but when it was taken up, they journeyed.

At the commandment of the LORD they rested in the tents, and at the commandment of the LORD they journeyed: they kept the charge of the LORD, at the commandment of the LORD by the hand of Moses.

And the LORD spake unto Moses, saying,

Make thee two trumpets of silver; of a whole piece shalt thou make them: that thou mayest use them for the calling of the assembly, and for the journeying of the camps.

And when they shall blow with them, all the assembly shall assemble themselves to thee at the door of the tabernacle of the congregation.

And if they blow [but] with one [trumpet], then the princes, [which are] heads of the thousands of Israel, shall gather themselves unto thee.

When ye blow an alarm, then the camps that lie on the east parts shall go forward.

When ye blow an alarm the second time, then the camps that lie on the south side shall take their journey: they shall blow an alarm for their journeys.

But when the congregation is to be gathered together, ye shall blow, but ye shall not sound an alarm.

And 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.

Also in the day of your gladness, and in your solemn days, and in the beginnings of your months, ye shall blow with the trumpets over your burnt offerings, and over the sacrifices of your peace offerings; that they may be to you for a memorial before your God: I [am] the LORD your God.

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

And the children of Israel took their journeys out of the wilderness of Sinai; and the cloud rested in the wilderness of Paran.

And they first took their journey according to the commandment of the LORD by the hand of Moses.

In the first [place] went the standard of the camp of the children of Judah according to their armies: and over his host [was] Nahshon the son of Amminadab.

And over the host of the tribe of the children of Issachar [was] Nethaneel the son of Zuar.

And over the host of the tribe of the children of Zebulun [was] Eliab the son of Helon.

And the tabernacle was taken down; and the sons of Gershon and the sons of Merari set forward, bearing the tabernacle.

And the standard of the camp of Reuben set forward according to their armies: and over his host [was] Elizur the son of Shedeur.

And over the host of the tribe of the children of Simeon [was] Shelumiel the son of Zurishaddai.
