12The Lord said to Moses and Aaron in the land of Egypt: 2This month shall mark for you the beginning of months; it shall be the first month of the year for you. 3Tell the whole congregation of Israel that on the tenth of this month they are to take a lamb for each family, a lamb for each household. 4If a household is too small for a whole lamb, it shall join its closest neighbour in obtaining one; the lamb shall be divided in proportion to the number of people who eat of it. 5Your lamb shall be without blemish, a year-old male; you may take it from the sheep or from the goats. 6You shall keep it until the fourteenth day of this month; then the whole assembled congregation of Israel shall slaughter it at twilight. 7They shall take some of the blood and put it on the two doorposts and the lintel of the houses in which they eat it. 8They shall eat the lamb that same night; they shall eat it roasted over the fire with unleavened bread and bitter herbs. 9Do not eat any of it raw or boiled in water, but roasted over the fire, with its head, legs, and inner organs. 10You shall let none of it remain until the morning; anything that remains until the morning you shall burn. 11This is how you shall eat it: your loins girded, your sandals on your feet, and your staff in your hand; and you shall eat it hurriedly. It is the passover of the Lord. 12For I will pass through the land of Egypt that night, and I will strike down every firstborn in the land of Egypt, both human beings and animals; on all the gods of Egypt I will execute judgements: I am the Lord. 13The blood shall be a sign for you on the houses where you live: when I see the blood, I will pass over you, and no plague shall destroy you when I strike the land of Egypt.
14 This day shall be a day of remembrance for you. You shall celebrate it as a festival to the Lord; throughout your generations you shall observe it as a perpetual ordinance. 15Seven days you shall eat unleavened bread; on the first day you shall remove leaven from your houses, for whoever eats leavened bread from the first day until the seventh day shall be cut off from Israel. 16On the first day you shall hold a solemn assembly, and on the seventh day a solemn assembly; no work shall be done on those days; only what everyone must eat, that alone may be prepared by you. 17You shall observe the festival of unleavened bread, for on this very day I brought your companies out of the land of Egypt: you shall observe this day throughout your generations as a perpetual ordinance. 18In the first month, from the evening of the fourteenth day until the evening of the twenty-first day, you shall eat unleavened bread. 19For seven days no leaven shall be found in your houses; for whoever eats what is leavened shall be cut off from the congregation of Israel, whether an alien or a native of the land. 20You shall eat nothing leavened; in all your settlements you shall eat unleavened bread.
