What is the definition of "Chelbo"?
Ramban #2: The Torah first instructs the Kohanim to offer all the Chelev of the Shelamim, then goes on to list all the parts that they need to sacrifice, both those that fall under the category of Chelev and those that don't. 3
Targum Onkelos: It means 'its Chelev'. Moshav Zekenim - after this, the Torah mentions all that is offered, both what is Chelev and what is not Chelev.
Ramban, Moshav Zekenim: "Chelev" is fatty membranes that peel from the animal's flesh easily. The tail is Shuman; it is closely attached to the flesh. Also, Shemos 29:22 mentions "ha'Chelev veha'Alyah" (the tail is not included in Chelev). It says here "Chelbo ha'Alyah Temimah", for when one removes the tail, much Chelev comes with it. Chelbo cannot mean its Chelev, because one may eat the tail of a Chulin animal (See Ramban, who elaborates. He also cites Chulin 117b,, and explains that although the tail is considered Chelev, the Torah only forbids Chelev that has the same Din regarding Shor, Keves and Ez, to preclude the tail).
Such as the Alyah and the two kidneys and the lobe of the liver (Ramban).
Why is the fat-tail described as "Temimah"?
