Chullin 3:7 - 4:1

ובחגבים – this is the sign of their pu- ity.

כל שיש לו ארבע רגלים וארבע כנפים ויש לו קרסולים (see Leviticus 11:21- jointed legs) – they are two long legs outside of the four. And they are adjacent to its neck, above from its legs to leap with them when it wishes to jump, it strengthens itself with them.

רבי יוסי אומר ושמו חגב – even though it has these four distinguishing marks, it is not kosher, other than if it is known that its name is locust. And this is the Halakha.

כל שיש לו סנפיר וקשקשת – even if it doesn’t have it now, and will in the future will grow one after a while, or that it has one now, and it will, in the future will drop it when it leaves the water (see Tractate Hullin 66a), it is permitted.

וסנפירין הפורח בהם – that roam–swim with them over the face of the water.

בהמה המקשה. מותר באכילה – [it is permitted to eat – when the dam is properly slaughtered] the entire fetus and even the place cutting of the limb. For if it put out its hoof–hand and didn’t retracted, one must leave it from what is inside to the outside and to cut it, for the place of the cut you have distinguished the outer part, but the inner part is prohibited, because it stands on the rim of the womb. But if it withdrew it (i.e., its hoof–hand), one does not need to cut to the inner side, but one confines and cuts and the place that one cut is permitted. For what is the reason that the limb is forbidden when it leaves to the outside? Because of (Exodus 22:30): “[You must not eat] flesh torn by beasts in the field.” Meat that left outside of its compartment which for it is a field, is “torn.” Just as something that is “torn,” once it was “torn,” furthermore has no permit, even meat, since it went outside of its compartment. And the place of the cut did not leave outside of its compartment; furthermore, it is permitted when it returns prior to the ritual slaughter, for we call it (Deuteronomy 14:6): “and any other animal [that has true hoofs which are cleft in two and brings up the cud] – such (an animal) you may eat.”

הרי הוא כילוד – and furthermore, he may not benefit from the ritual slaughter of its mother, and he requires a ritual slaughter of its own if he is found living. But if he (i.e., the offspring) is found dead, it is like something that died of itself.

חותך מעובר שבמעיה – and he left the piece within her, it is permitted with the ritual slaughter of the animal and is not forbidden because of “the limb from a living animal” (one of the seven Noahide commandments).
