Exodus 12:43-51

43And the Lord said to Moses and Aaron, “This is the ordinance of the Passover: No foreigner shall eat it.

44But every man’s servant who is bought for money, when you have circumcised him, then he may eat it.

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

46In one house it shall be eaten; you shall not carry any of the flesh outside the house, nor shall you break one of its bones.

47All the congregation of Israel shall keep it.

48And when a stranger dwells with you and wants to 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 a native of the land. For no uncircumcised person shall eat it.

49One law shall be for the native-born and for the stranger who dwells among you.”

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

51And it came to pass, on that very same day, that the Lord brought the children of Israel out of the land of Egypt according to their armies.
