Parallel
Numbers 10:6
Clementine Vulgate · Berean Standard Bible
In secundo autem sonitu et pari ululatu tubæ, levabunt tentoria qui habitant ad meridiem ; et juxta hunc modum reliqui facient, ululantibus tubis in profectionem.
When you sound the short blasts a second time, the camps that lie on the south side are to set out. The blasts are to signal them to set out.
