Exodus 12:21-28 Then Mosheh calls for all the elders of Yisra El and says to them, Draw out and take of the flock for your families and slaughter the pasach:

ECB⁽ⁱ⁾ ²¹ Then Mosheh calls for all the elders of Yisra El and says to them, Draw out and take of the flock for your families and slaughter the pasach: ²² and take a bundle of hyssop and dip it in the blood in the bason: and touch the lintel and the two side posts with the blood in the bason: and no man of you goes out at the portal of his house until morning: ²³ for Yah Veh passes through to smite the Misrayim; and when he sees the blood on the lintel and on the two side posts, Yah Veh leaps over the portal and gives not that the ruiner come in to your houses to smite you. ²⁴ And you guard this word for an eternal statute - to you and to your sons. ²⁵ And so be it, when you come to the land Yah Veh gives you, as he worded, that you guard this service. ²⁶ And so be it, when your sons say to you, What is this service you have? ²⁷ That you say, It is the sacrifice of the pasach of Yah Veh, who leaped over the houses of the sons of Yisra El in Misrayim when he smote the Misrayim and rescued our houses. - and the people bow and prostrate. ²⁸ And the sons of Yisra El go and work as Yah Veh misvahed Mosheh and Aharon - thus they work.
