Parashas Bechukosai · beginning of tochacha · Passuk 14 · Unit 2
Torah Temimah cites Toras Kohanim on the force of the word li.
English: Why does Scripture say “to Me”? It refers only to one who knows his Master and intends to rebel against Him.
Intentional-rebellion derasha on the pronoun li.
The severity of the tochacha is directed at knowing, deliberate defiance — not mere ignorance.
