Exodus 12:44-48

44But every man’s servant that is bought for money, when thou hast circumcised him, then shall he eat thereof.

45A foreigner and an hired servant shall not eat thereof.

46In 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.

47All the congregation of Israel shall keep it.1

48And when a stranger shall sojourn with thee, and will keep the passover to Yhwh, 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.
