Numbers 10:4 Meaning and Commentary

Numbers 10:4

And if they blow [but] with one [trumpet]
With only one of them, or but once, with one sounding, and that an even one as before:

then the princes, [which are] the heads of the thousands of Israel,
shall gather themselves unto thee:
and they only or alone, as Aben Ezra: by this token, or by this difference of blowing both trumpets, or only one, it was, easily known when the whole congregation or when the princes only were to meet Moses at the same place, the door of the tabernacle of the congregation; and all are to attend divine service, and the ministry of the word, even the whole church of God, and all the members of it, high and low, rich and poor, princes and people.

Numbers 10:4 In-Context

2 Make two silver trumpets; you shall make them of hammered work; and you shall use them for summoning the congregation, and for breaking camp.

3 When both are blown, the whole congregation shall assemble before you at the entrance of the tent of meeting.

4 But if only one is blown, then the leaders, the heads of the tribes of Israel, shall assemble before you.

5 When you blow an alarm, the camps on the east side shall set out;

6 when you blow a second alarm, the camps on the south side shall set out. An alarm is to be blown whenever they are to set out.
