Numbers 10:4-13

⁴If only one of them is sounded, then the chiefs, the heads of the thousands of Israel, are to come to you.

⁵When a loud note is sounded, the tents placed on the east side are to go forward.

⁶At the sound of a second loud note, the tents on the south side are to go forward: the loud note will be the sign to go forward.

⁷But when all the people are to come together, the horn is to be sounded but not loudly.

⁸The horns are to be sounded by the sons of Aaron, the priests; this is to be a law for you for ever, from generation to generation.

⁹And if you go to war in your land against any who do you wrong, then let the loud note of the horn be sounded; and the Lord your God will keep you in mind and give you salvation from those who are against you.

¹⁰And on days of joy and on your regular feasts and on the first day of every month, let the horns be sounded over your burned offerings and your peace-offerings; and they will put the Lord in mind of you: I am the Lord your God.

¹¹Now in the second year, on the twentieth day of the second month, the cloud was taken up from over the Tent of witness.

¹²And the children of Israel went on their journey out of the waste land of Sinai; and the cloud came to rest in the waste land of Paran.

¹³They went forward for the first time on their journey as the Lord had given orders by the hand of Moses.
