Exodus 12:14-28 And that day shall be to you for a memorial. And you shall celebrate it as a festival to the Lord throughout all your generations. As an everlasting ordinance you shall celebrate it.

Thomson⁽ⁱ⁾ ¹⁴ And that day shall be to you for a memorial. And you shall celebrate it as a festival to the Lord throughout all your generations. As an everlasting ordinance you shall celebrate it. ¹⁵ Seven days you shall eat unleavened bread. And from the first day you shall remove all leaven out of your houses. Whoever shall eat leaven from the first to the seventh day, that soul shall be cut off from among Israel. ¹⁶ And with regard to the first day, it shall be proclaimed holy; and the seventh day shall be holy to you. In them you shall not do any kind of sacrificial service, save that which must be done for every soul. This alone shall be done for you ¹⁷ and you shall keep this commandment. For on that day I will lead out your host from the land of Egypt; therefore you shall make the observance of that day an everlasting rite to your generations. ¹⁸ Beginning at evening with the fourteenth day of the first month, you shall eat unleavened bread until the evening of the twenty first day. ¹⁹ For seven days there must be no leaven found in your houses. Whoever shall eat leavened bread, that soul shall be cut off from among the congregation of Israel; whether he be a stranger or born in the land. ²⁰ You shall eat nothing that is leavened. But in all your habitations you must eat unleavened bread. ²¹ Moses therefore convened the whole senate of the children of Israel and said to them, Go take for yourselves the sheep according to your families and kill the passover; ²² and ye shall take a bunch of hyssop and having dipped it in the blood by the door you shall smear the lintel and the two side posts with some of the blood which is at the door; and none of you shall go out of the door of his house until the morning. ²³ For the Lord will pass by to smite the Egyptians; and when he shall see the blood on the lintel and on the two side posts, the Lord will pass over that door and will not suffer the destroyer to enter into your houses to smite. ²⁴ And this ordinance you shall keep as a rite established for thee and thy children for ever. ²⁵ And when you come to the land which the Lord will give you as he hath spoken, you must keep up this religious service. ²⁶ And if your children say to you, What is the meaning of this religious service? ²⁷ then you shall say to them, It is the sacrifice of the Passover of the Lord; because he passed over the houses of the Israelites in Egypt when he smote the Egyptians, and delivered our houses. Upon which the people bowed down and worshipped; ²⁸ and the Israelites went and did as the Lord commanded Moses and Aaron.
