How many necks did Binyamin have: We do not follow [teach] this version. For this is the way of Scripture, to write, "necks," in the plural form, [as in] (Genesis 27:17), "upon the flat of his necks." [So here too] - "he cried upon his necks."

פרט לחיה ולעוף ולבהמה טמאה – a “kid,” excluding fowl which is not cattle. A “kid,” excluding a beast of chase, and even though a beast of chase is included within cattle. An additional Biblical verse comes to exclude it. A “kid,” and not unclean cattle, and we derive if from what is written (Genesis 27:16): “with the skins of the kids;” “Judah sent the kid [by his friend the Adullamite]” (Genesis 38:20) – here the Biblical verse explains to you that this “kid” is from the goats. But if he did not explain this, there is by implication, even the rest of the cattle, hence it was necessary for him to explain this.
