Leviticus 26:36

והבאתי מרך AND I WILL SEND A FAINTNESS [INTO THEIR HEART] — מרך‎ means timidity and faint-heartedness. The מ is an essential letter of the noun, which, however, is omitted in the root; as is the case with the מ in the nouns מועד and ומוקש. ונסו מנוסת חרב AND THEY SHALL RUN AWAY AS RUNNING AWAY FROM THE SWORD — as though pursuers were about to kill them. עלה נדף A RUSTLING LEAF — i. e. a leaf which the wind pushes along and beats it against another leaf, so that, in tapping it, it produces a sound. This, too, is its translation in the Targum: the sound of a leaf דשקיף — a term that signifies beating. The words (Genesis 41:6): שדופות קדים are rendered in the Targum by שקיפן קידום, beaten by the east wind, the first word being of the same meaning as משקוף, a lintel, that being the place against which the door beats. Similarly the Targum translation of חבורה, a wound, (Exodus 21:25), is משקופי (a spot that has been beaten).

וְהַנִּשְׁאָרִ֣ים בָּכֶ֔ם וְהֵבֵ֤אתִי מֹ֙רֶךְ֙ בִּלְבָבָ֔ם בְּאַרְצֹ֖ת אֹיְבֵיהֶ֑ם וְרָדַ֣ף אֹתָ֗ם ק֚וֹל עָלֶ֣ה נִדָּ֔ף וְנָס֧וּ מְנֻֽסַת־חֶ֛רֶב וְנָפְל֖וּ וְאֵ֥ין רֹדֵֽף׃

And upon those who are left alive of you I will send a faintness into their hearts in the lands of their enemies; and the sound of a shaken leaf shall chase them; and they shall flee, as fleeing from a sword; and they shall fall when none pursues.
