Exodus 12:27-30King James Version (KJV)
27 That ye shall say, It is the sacrifice of the Lord's passover, who passed over the houses of the children of Israel in Egypt, when he smote the Egyptians, and delivered our houses. And the people bowed the head and worshipped.
28 And the children of Israel went away, and did as the Lord had commanded Moses and Aaron, so did they.
29 And it came to pass, that at midnight the Lord smote all the firstborn in the land of Egypt, from the firstborn of Pharaoh that sat on his throne unto the firstborn of the captive that was in the dungeon; and all the firstborn of cattle.
30 And Pharaoh rose up in the night, he, and all his servants, and all the Egyptians; and there was a great cry in Egypt; for there was not a house where there was not one dead.
Exodus 12:43-46King James Version (KJV)
43 And the Lord said unto Moses and Aaron, This is the ordinance of the passover: There shall no stranger eat thereof:
44 But every man's servant that is bought for money, when thou hast circumcised him, then shall he eat thereof.
45 A foreigner and an hired servant shall not eat thereof.
46 In one house shall it be eaten; thou shalt not carry forth ought of the flesh abroad out of the house; neither shall ye break a bone thereof.
