Thomson⁽ⁱ⁾ 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.
