Numbers 10:1-3 New English Translation (NET Bible)
The Blowing of Trumpets
10 The Lord spoke to Moses: 2 “Make two trumpets of silver; you are to make them from a single hammered piece. You will use them for assembling the community and for directing the traveling of the camps. 3 When they blow them both, all the community must come to you to the entrance of the tent of meeting.
