Pesachim 7:11 - 7:12

כל הנאכל בשור הגדול – that already had become distasteful, all in the future will get harder.

יאכל בגדי הרך – appropriate for eating on Passover all eight days. But what is not eaten with a large ox, is not registered upon it during Passover, even though that it is soft now, since it will get hard over the course of time.

וראשי כנפים וסחוסים – This is how it should be read: And that which is eaten of the big ox – the ends of the shoulder blades, the gristles, which we call טנרוס /TANROS in the foreign language that are at the head of the shoulder blade and the rest of the gristles such as the ear-lobe and the gristles of the breast and the small ribs at the end of the spine, since the big ox which is eaten by boiling, they eat the soft lamb roasted.

אבל המותיר בטהור וכו' – as it is written (Exodus 12:10): “You may not leave any of it over until morning; if any of it is left until morning, you shall burn it.” The Biblical verses comes to give a positive commandment after a negative commandment, to say that if you transgressed the negative commandment, fulfill the positive command and you won’t be flogged. Alternatively, since it is a negative commandment which has no action with it, and any negative commandment that doesn’t have an action associated with it, one is not flogged for it.

והשובר בטמא וכו' – as it is written (Exodus 12:46): “nor shall you break a bone of it,” a kosher/fit individual is warned on the breaking of a bone, but he is not warned on the breaking of a bone of something invalid.

A limb from the Paschal sacrifice.

Part of [a limb] left [the group's] boundaries, and it is necessary to chop the portion that exited; as it says (Exodus 22) "And meat that was torn (died without slaughter) in the field you should not eat," this is explained to refer to any flesh that was left out in the field i.e. it left it's boundaries; Like holy of holies that went beyond the courtyard or lesser holies that exited Jerusalem: that meat that left is considered "torn" and you should not eat it.

Cut the part of the meat that exited in a circle until the bone.

And peel the meat that didn't depart until it reaches the joint, and eat the peeled meat since it did not exit, and chop the joint and send off the entire bone of which part left the boundary.

And with mukdashim: other sacrifices sans the paschal sacrifice cleave the portion that exited (through the bone) with a cleaver. With the paschal sacrifice it is forbidden to do this, since it is prohibited from having a bone broken.

From the door-wing and inside: A door-wing is any place where the door closes i.e. the place that the door overlaps and taps when it is closed. (This is the inner lip of thick portion of the door until the spot of closure. From the wing inwards.) This is entirely inside the city.

As inside: and eat there the lesser holies.

From the door-wing and towards the outside: This is from the point of closure outwards, it is considered outside.

The windows that are in the walls of Jerusalem. And the thickness of the top of the wall in the roof, is considered like the inside.
