Parashas Haazinu · Passuk 32:4
Torah Temima points to the statement of Rabbi Chanina.
English: Rabbi Chanina said: Anyone who says that the Holy One is a “vatran” (one who casually overlooks), let his life be forfeit, as it is said “The Rock, His work is perfect, for all His ways are justice.”
A strict affirmation of divine justice derived from the description of Hashem as the perfect Rock.
The verse leaves no room for the claim that Hashem simply overlooks wrongdoing. Every path is justice. The derasha therefore rejects any theology that would encourage a person to sin while relying on divine leniency.
