Numbers 10:7-12

⁷And whenever ye shall gather the assembly, ye shall sound, but not an alarm.

⁸And the priests the sons of Aaron shall sound with the trumpets; and it shall be a perpetual ordinance for you throughout your generations.

⁹And if ye shall go forth to war in your land against your enemies that are opposed to you, then shall ye sound with the trumpets; and ye shall be had in remembrance before the Lord, and ye shall be saved from your enemies.

¹⁰And in the days of your gladness, and in your feasts, and in your new moons, ye shall sound with the trumpets at your whole-burnt-offerings, and at the sacrifices of your peace-offerings; and there shall be a memorial for you 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, the cloud went up from the tabernacle of witness.

¹²And the children of Israel set forward with their baggage in the wilderness of Sina; and the cloud rested in the wilderness of Pharan.
