The Bible
Exodus 12
The Lord institutes the Passover and the Feast of Unleavened Bread—Lambs without blemish are slain—Israel is saved by their blood—The firstborn of all Egyptians are slain—Israel is thrust out of Egypt after 430 years—No bones of the paschal lambs are to be broken.
1And the Lord spake unto Moses and Aaron in the land of Egypt, saying,
20Ye shall eat nothing leavened; in all your habitations shall ye eat unleavened bread.
24And ye shall observe this thing for an ordinance to thee and to thy sons for ever.
26And it shall come to pass, when your children shall say unto you, What mean ye by this service?
32Also take your flocks and your herds, as ye have said, and be gone; and bless me also.
38And a mixed multitude went up also with them; and flocks, and herds, even very much cattle.
45A foreigner and an hired servant shall not eat thereof.
47All the congregation of Israel shall keep it.
49One law shall be to him that is homeborn, and unto the stranger that sojourneth among you.
50Thus did all the children of Israel; as the Lord commanded Moses and Aaron, so did they.
