12 Following the imperatival forms in v. 6, the prefixed verbal form is understood as a jussive expressing the psalmist’s wish. Another option is to take the form as an imperfect (indicative) and translate, “they will scatter” (see v. 9). The verb מָאַס (ma’as; which is a homonym of the more common מָאַס, “to refuse, reject”) appears only here and in Job 7:5, where it is used of a festering wound from which fluid runs or flows.
13 Heb “like water, they go about for themselves.” The translation assumes that the phrase “they go about for themselves” is an implied relative clause modifying “water.” Another option is to take the clause as independent and parallel to what precedes. In this case the enemies would be the subject and the verb could be taken as jussive, “let them wander about.”
14 The syntax of the Hebrew text is difficult and the meaning uncertain. The text reads literally, “he treads his arrows (following the Qere; Kethib has “his arrow”), like they are cut off/dry up.” It is not clear if the verbal root is מָלַל (malal, “circumcise”; 576 IV מָלַל) or the homonymic מָלַל (“wither”; I מלל). Since the verb מָלַל (“to wither”) is used of vegetation, it is possible that the noun חָצִיר (khatsir, “grass,” which is visually similar to חִצָּיו, khitsayv, “his arrows”) originally appeared in the text. The translation above assumes that the text originally was כְּמוֹ חָצִיר יִתְמֹלָלוּ(kémo khatsir yitmolalu, “like grass let them wither”). If original, it could have been accidentally corrupted to חִצָּיר כְּמוֹ יִתְמֹלָלוּ (“his arrow(s) like they dry up”) with דָּרַךְ (darakh, “to tread”) being added later in an effort to make sense of “his arrow(s).”
