17 And ye shall be shomer to safeguard the matzot; for on this very day I brought your tzva'os out of Eretz Mitzrayim; therefore shall ye be shomer over this day in your generations by a chukkat olam.
18 In the first month, on the fourteenth day of the month at erev, ye shall eat matzot, until the one and twentieth day of the month at erev.
19 Shivat yamim shall there be no se'or (yeast, leaven) found in your batim (houses); whosoever eateth that which is leavened, even that nefesh shall be cut off from Adat Yisroel, whether he be a ger, or native born in ha'aretz.
20 Ye shall eat nothing leavened; in all your dwellingplaces shall ye eat matzot.
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.
