Ibn Ezra on Leviticus 26:36

הנשארים בכם. בעבור שאמר והריקותי אחריכם חרב: AND AS FOR THEM THAT ARE LEFT OF YOU. Scripture says this because it previously stated, and I will draw out the sword after you (v. 33).¹²¹And as for them that are left of you (v. 36) refers to those who survive the sword’s destruction.

מורך מפעלי הכפל וכן במועל ידיה׳‎ מגזרת ורך הלבב ויפחדו עד שירדפם קול עלה נדף והוא שם התאר מבנין נפעל ונו״ן השרש מובלע: A FAINTNESS. Morekh (faintness) comes from a double root.¹²²It comes from the root resh, kaf, kaf. Similarly, the word mo’al (lifting up) in with the lifting up of their hands (Neh. 8:6).¹²³From the root ayin, lamed, lamed. The word morekh is related to the word rakh (faint) in and faint-hearted (Deut. 20:8). They will be so scared that the sound of a driven leaf shall chase them. Niddaf (driven) is an adjective in the nifal. The root nun is swallowed.¹²⁴The root of niddaf is nun, dalet, peh. The nun in niddaf is the root of the nifal form.
