21 Then Moshe called for all the Ziknei Yisroel, and said unto them, Draw out as separate and take for yourselves a lamb according to your mishpokhot, and slaughter (shachat) the Pesach [offering, i.e., Pesach lamb (see Yeshayah 53:7)].
22 And ye shall take a bunch of hyssop, and dip it in the dahm that is in the basin, and strike the mashkof (lintel) and the two mezuzot (door sideposts) with the dahm that is in the basin; and none of you shall go out the door of his bais until boker.
23 For Hashem will pass through to strike the Mitzrayim; and when He seeth the dahm upon the mashkof, and on the two mezuzot, Hashem will pasach (pass over, spare, skip) the entrance, and will not permit the Mashkhit (Destroyer, i.e., Hashem's emissary of judgment, [see Num 22:31 on the Malach Hashem]) to enter unto your batim to strike.
24 And ye shall be shomer over this word as a chok (ordinance) to thee and your children ad olam (forever).
25 And it shall come to pass, when ye come to ha'aretz which Hashem will give to you, according as He hath promised, that ye shall be shomer over this avodah.
26 And it shall come to pass, when your banim shall say unto you, Mah haavodah hazot lachem (What is this avodah to you)?
27 That ye shall say, It is the zevach of Hashem's Pesach, who pasach (passed over, skipped, spared) the batim (households) of the Bnei Yisroel in Mitzrayim, when He struck down the Egyptians, and spared bateinu (our houses). And the people bowed down and worshiped.
