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 sojourner and a hired servant shall not eat thereof. 46In one house shall it be eaten; thou shalt not carry forth aught of the flesh abroad out of the house; neither shall ye break a bone thereof. 47All the congregation of Israel shall keep it. 48And when a stranger shall sojourn with thee, and will keep the passover to Jehovah, 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: but no uncircumcised person shall eat thereof.
