Exodus 12:46

In one house shall it be eaten, and ye shall not carry of the flesh out from the house; and a bone of it ye shall not break.

In one house shall it be eaten; thou shalt not carry forth ought of the flesh abroad out of the house; neither shall ye break a bone thereof.

It must be eaten in one house. You shall not carry any of the meat outside of the house. Do not break any of its bones.
