“For it is a chatas” — a chatas is called minchah and a minchah is called chatas; this creates a reciprocal hekesh for rules of designation.
In the sugya: The identification of this flour offering as “chatas” creates a two-way hekesh between ordinary chatas rules and this minchah. Wrong intention that invalidates a chatas therefore also invalidates the flour offering.
Type of Learning
Hekesh of minchah-chatas and chatas-minchah in both directions for rules of designation.
What Is Learned
Wrong designation (she-lo lishmah) that ruins a chatas also ruins this flour offering. Because the Torah itself calls the flour “chatas,” the laws of proper intention that govern animal chatas are transferred to the minchah as well.
