Exodus 12:13-28 And the blood shall be for a sign to you on the houses in which you are, and I will see the blood, and will protect you, and there shall not be on you the plague of destruction, when I smite in the land of Egypt.

CAB⁽ⁱ⁾ ¹³ And the blood shall be for a sign to you on the houses in which you are, and I will see the blood, and will protect you, and there shall not be on you the plague of destruction, when I smite in the land of Egypt. ¹⁴ And this day shall be to you a memorial, and you shall keep it a feast to the Lord through all your generations; you shall keep it a feast for a perpetual ordinance. ¹⁵ Seven days you shall eat unleavened bread, and from the first day you shall utterly remove leaven from your houses: whoever shall eat leaven, that soul shall be utterly destroyed from Israel, from the first day until the seventh day. ¹⁶ And the first day shall be called holy, and the seventh day shall be a holy convocation to you. You shall do no servile work on them, only as many things as is necessary shall be done by every soul, this only shall be done by you. ¹⁷ And you shall keep this commandment, for on this day will I bring out your force out of the land of Egypt; and you shall make this day a perpetual ordinance for you throughout your generations. ¹⁸ Beginning the fourteenth day of the first month, you shall eat unleavened bread from evening, till the twenty-first day of the month, till evening. ¹⁹ Seven days leaven shall not be found in your houses; whosoever shall eat anything leavened, that soul shall be cut off from the congregation of Israel, both among the occupiers of the land and the original inhabitants. ²⁰ You shall eat nothing leavened, but in every habitation of yours you shall eat unleavened bread. ²¹ And Moses called all the elders of the children of Israel, and said to them, Go away and take to yourselves a lamb according to your families, and slay the Passover lamb. ²² And you shall take a bunch of hyssop, and having dipped it into some of the blood that is by the door, you shall touch the lintel, and shall put it upon both doorposts, even of the blood which is by the door; but none of you shall go out of the door of his house until morning. ²³ And the Lord shall pass by to smite the Egyptians, and shall see the blood upon the lintel, and upon the doorposts; and the Lord shall pass over the door, and shall not allow the destroyer to enter into your houses to kill you. ²⁴ And keep this thing as an ordinance for yourself and for your children forever. ²⁵ And if you should enter into the land which the Lord shall give you, as He has spoken, keep this service. ²⁶ And it shall come to pass, if your sons say to you, What is this service? ²⁷ That you shall say to them, This Passover is a sacrifice to the Lord, as He defended the houses of the children of Israel in Egypt, when He struck the Egyptians, but delivered our houses. ²⁸ And the people bowed and worshipped. And the children of Israel departed and did as the Lord commanded Moses and Aaron, so did they.
