Numbers 10:9

10:9 If you go to war in your land against an adversary who opposes17 you, then you must sound an alarm with the trumpets, and you will be remembered before the Lord your God, and you will be saved18 from your enemies.

17	tn Both the “adversary” and “opposes” come from the same root: צָרַר (tsarar), “to hem in, oppress, harass,” or basically, “be an adversary.”
18	tn The Niphal perfect in this passage has the passive nuance and not a reflexive idea—the Israelites would be spared because God remembered them.
