מָרַץ a root not used in Kal, the primary meaning of which has been often discussed. I have, however, no doubt that the truth was seen by Kimchi, who regarded as its primary power to be strong, forcible; for this not only very well suits all the passages, but it is confirmed by the kindred פָּרַץ (m and p interchanged), to be violent (Hosea 4:2); whence פָּרִיץ a violent man. The meaning appears to be secondary, and taken from the idea of hard labour, which is found in Arabic مَرِضَ to languish, to be sick (prop. wearied out with toil).
[In Thes. the meaning preferred is that given by Cocceius and J. Simonis, to be fierce; hence, to be vehement.]
Niphal, Job 6:25, מַה־נִּמְרְצוּ אִמְרֵי־ישֶׂר “how powerful are right words;” 1 Kings 2:8, קְלָלָה נִמְרֶצֶת “a heavy (or grievous) curse,” Micah 2:10. חֶבֶל נִמְרָץ “very violent destruction.”
Hiphil, to make vehement, to irritate; Job 16:3, מַה־יַּמְרִיצְךָ “what (so) irritateth thee?”
