Exodus 12:43 BBE

⁴¹  And at the end of four hundred and thirty years, to the very day, all the armies of the Lord went out of the land of Egypt.

⁴²  It is a watch-night before the Lord who took them out of the land of Egypt: this same night is a watch-night to the Lord for all the children of Israel, through all their generations.

⁴³  And the Lord said to Moses and Aaron, This is the law of the Passover: no man who is not an Israelite is to take of it:

⁴⁴  But every man's servant, whom he has got for money, may take of it, when he has had circumcision.

⁴⁵  A man from a strange country living among you, and a servant working for payment, may not take part in it.
