10:5 When you blow an alarm, ³  then the camps that are located ⁴  on the east side must begin to travel. ⁵ 

[1:5]  ¹ tn The verb is עָמַד (’amad, “to stand”). It literally then is, “who will stand with you.” They will help in the count, but they will also serve as leaders as the camp moves from place to place.

[1:5]  ² tn The preposition lamed (ל) prefixed to the name could be taken in the sense of “from,” but could also be “with regard to” (specification).

[10:5]  ³ tn The word for an alarm is תְּרוּעָה (tÿru’ah). The root verb of this word means “to give a blast on the trumpet.” It may also on occasion mean “give a shout” in battle (Josh 6:10). In this passage it must refer to the sound of the trumpet.

[10:5]  ⁴ tn Heb “the camps that are camping.”

[10:5]  ⁵ tn The perfect tense with vav (ו) consecutive functions as the equivalent of the imperfect tense. Here the emphasis is on the start of the journey.
