New King James Version (NKJV)
Exodus 12
47 All the congregation of Israel shall keep it.
48 And 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.
49 One law shall be for the native-born and for the stranger who dwells among you."
50 Thus all the children of Israel did; as the Lord commanded Moses and Aaron, so they did.
51 And 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.
Exodus 13
1 Then the Lord spoke to Moses, saying,
2 "Consecrate to Me all the firstborn, whatever opens the womb among the children of Israel, both of man and beast; it is Mine."
3 And Moses said to the people: "Remember this day in which you went out of Egypt, out of the house of bondage; for by strength of hand the Lord brought you out of this place. No leavened bread shall be eaten.
4 On this day you are going out, in the month Abib.
5 And it shall be, when the Lord brings you into the land of the Canaanites and the Hittites and the Amorites and the Hivites and the Jebusites, which He swore to your fathers to give you, a land flowing with milk and honey, that you shall keep this service in this month.
6 Seven days you shall eat unleavened bread, and on the seventh day there shall be a feast to the Lord.
