Exodus 12:47

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

45 A sojourner and a hired servant shall not eat thereof.

46 In 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.

47 All the congregation of Israel shall keep it.

48 And 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.

49 One law shall be to him that is home-born, and unto the stranger that sojourneth among you.

50 Thus did all the children of Israel; as Jehovah commanded Moses and Aaron, so did they.
