Commentaire sur Le Lévitique 26:21

ואם תלכו עמי קרי — Our Rabbis said (Sifra, Bechukotai, Chapter 5 5): this word signifies “irregularly”, “by chance” (מקרה), which is a thing that happens only occasionally; thus this means: if you will follow the commandments irregularly. Menachem explains it as an expression for “refraining”. Similar is, (Proverbs 25:17) “Refrain (הוקר) thy foot [from thy neighbour’s house]”; (Proverbs 17:27) “of a refraining (יקר) spirit”. This meaning approximates to the translation given by Onkelos which is a term denoting “stubbornness” (קושי) — that they harden their hearts so as to refrain from coming near unto Me.

ואם תלכו עמי קרי, "and if you walk contrary unto Me, etc." Inasmuch as the afflictions which have been visited upon the Jewish people are clearly the hand of G'd, their failure to react is described as walking contrary to G'd.

ואם תלכו עמי קרי, Menachem interprets the word קרי as related to Proverbs 28,17 הוקר רגלך, “restrain your foot.” This is nonsense. The word הוקר in Proverbs is derived from a group of verbs known as פ'ה, first root letter being the letter ה, as in Genesis 47,6 הושב את אביך, a transitive mode of the root ישב, meaning: “settle your father, etc.” The word קרי is derived from the root קרה as in Numbers 23,15, meaning: “if you will walk with Me as if your fate is subject to coincidences, totally arbitrary happenings, not subject to providence, as a person who walks haphazardly, not following a definitive direction.”
