Or, si vous ne dépossédez pas à votre profit tous les habitants de ce pays, ceux que vous aurez épargnés seront comme des épines dans vos yeux et comme des aiguillons à vos flancs: ils vous harcèleront sur le territoire que vous occuperez;

Troops [and] snares Heb. צנים, as in (Num. 33:55) “troops (לצנינים) in your sides”; (Ezek. 23: 24) “And they will come upon you, a band (הצן),” an expression of bands and brigands.

weapons [Heb. הֹצֶן]. Dunash (p. 59) explained it as one type of weapon, but I say that it is an expression of the surroundings of camps like (Num. 33:55): “and camps (וְלִצְנִינִים) in your sides,” [which Onkelos renders:] and camps surrounding you. Menachem (p. 150) explains הֹצֶן like (Ps. 91:4): “His truth is an encompassing shield (צִנָה וְסֹחֵרָה), but Dunash does not agree with him, and the Targum supports Dunash, rendering: they will come upon you with weapons. הֹצֶן is like בְּהֹצֶן, with weapons, and הֹצֶן could mean the same as חֹצֶן, from (Isa. 49:22): “and they shall bring your sons בְּחֹצֶן,”which means with the arm, and so too: “And they will come upon you הֹצֶן,” meaning [as with] an army, as (Dan. 11:15), “and the arms (וּזְרוֹעוֹת) of the south,” meaning the armies of the south.
