New King James Version (NKJV)
Numbers 9
21 So it was, when the cloud remained only from evening until morning: when the cloud was taken up in the morning, then they would journey; whether by day or by night, whenever the cloud was taken up, they would journey.
22 Whether it was two days, a month, or a year that the cloud remained above the tabernacle, the children of Israel would remain encamped and not journey; but when it was taken up, they would journey.
23 At the command of the Lord they remained encamped, and at the command of the Lord they journeyed; they kept the charge of the Lord, at the command of the Lord by the hand of Moses.
Numbers 10
1 And the Lord spoke to Moses, saying:
2 "Make two silver trumpets for yourself; you shall make them of hammered work; you shall use them for calling the congregation and for directing the movement of the camps.
3 When they blow both of them, all the congregation shall gather before you at the door of the tabernacle of meeting.
4 But if they blow only one, then the leaders, the heads of the divisions of Israel, shall gather to you.
5 When you sound the advance, the camps that lie on the east side shall then begin their journey.
6 When you sound the advance the second time, then the camps that lie on the south side shall begin their journey; they shall sound the call for them to begin their journeys.
7 And when the assembly is to be gathered together, you shall blow, but not sound the advance.
8 The sons of Aaron, the priests, shall blow the trumpets; and these shall be to you as an ordinance forever throughout your generations.
