Exodus 12:44-48

But every man’s servant that is bought for money, when thou hast circumcised him, then shall he eat thereof.

A foreigner and an hired servant shall not eat thereof.

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.

All the congregation of Israel shall keep it.

And when a stranger shall sojourn with thee, and will keep the passover to the LORD, let all his males be circumcised, and then let him come near and keep it; and he shall be as one that is born in the land: for no uncircumcised person shall eat thereof.
