6 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.
6 At the sounding of a second blast, the camps on the south are to set out. The blast will be the signal for setting out.
6 And when you blow an alarm the second time, the camps that are on the south side shall set out. An alarm is to be blown whenever they are to set out.
6 At the second blast the camps on the south set out. The long blasts are the signals to march.
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.
6 When you sound the signal a second time, the tribes camped on the south will follow. You must sound short blasts as the signal for moving on.

Commentary on Numbers 10:1-10
(Read Numbers 10:1-10)
Here are directions concerning the public notices to be given the people by sound of trumpet. Their laws in every case were to be Divine, therefore, even in this matter Moses is directed. These trumpets typify the preached gospel. It sounds an alarm to sinners, calls them to repent, proclaims liberty to the captives and slaves of Satan, and collects the worshippers of God. It directs and encourages their heavenly journey; stirs them up to combat against the world and sin, encouraging them with the assurance of victory. It leads their attention to the sacrifice of Christ, and shows the Lord's presence for their protection. It is also necessary that the gospel trumpet give a distinct sound, according to the persons addressed, or the end proposed; whether to convince, humble, console, exhort, reprove, or teach. The sounding of the trumpet of the gospel is God's ordinance, and demands the attention of all to whom it is sent.
