Exodus 12:46

בבית אחד יאכל IN ONE HOUSE SHALL IT BE EATEN — in one company (cf. שה לבית); meaning that those who have registered themselves for it (the Paschal offering) shall not form themselves afterwards into two companies and divide it. An objection was raised: You say that this means “in one company”, but perhaps this is not so, but it means “in one house” (or place) as it usually signifies, and it intends to teach that if they had begun to eat, for example, in the courtyard of a house and rain fell they may not enter the house to complete the eating of the offering? The reply was given: this cannot be so, because Scripture says, (v. 7) “[They shall put the blood] upon the houses (plural) wherein they shall eat it” — and from here it follows that one who is eating the Paschal offering may eat it in two places (consequently the only meaning of the term בית is “company”, as was suggested) (cf. Mekhilta and Onkelos). לא תוציא מן הבית THOU SHALT NOT CARRY FORTH OUT OF THE HOUSE this must therefore mean away from the company (Mekhilta). ועצם לא תשברו בו NEITHER SHALL YE BREAK A BONE THEREOF — any bone that is fitted for eating (for the purpose of the performing the command of eating the Paschal lamb) as, for instance, one upon which there is flesh of the size of an olive — to it there is (applies) the prohibition relating to the breaking of a bone, but if there is not upon it flesh of the size of an olive there does not apply to it the prohibition of breaking a bone (cf. Pesachim 84b).

בְּבַ֤יִת אֶחָד֙ יֵאָכֵ֔ל לֹא־תוֹצִ֧יא מִן־הַבַּ֛יִת מִן־הַבָּשָׂ֖ר ח֑וּצָה וְעֶ֖צֶם לֹ֥א תִשְׁבְּרוּ־בֽוֹ׃

In one house shall it be eaten: thou shalt not take any of the meat outside, out of the house; neither shall you break a bone of it.
