Exodus 12:12-17

12For I will go through the landH776 of EgyptH4714 in that nightH3915, and will smite all the first-born in the landH776 of EgyptH4714, both manH120 and beast; and against all the godsH430 of EgyptH4714 I will execute judgmentsH8201: I am Jehovah. 13And the bloodH1818 shall beH1961 to you for a token upon the housesH1004 whereH834 ye are: and when I seeH7200 the bloodH1818, I will pass over you, and there shall no plagueH5063 beH1961 upon you to destroy you, when I smite the landH776 of EgyptH4714. 14And this dayH3117 shall beH1961 unto you for a memorialH2146, and ye shall keep it a feastH2282 to Jehovah: throughout your generationsH1755 ye shall keep it a feastH2282 by an ordinance for everH5769.

15SevenH7651 daysH3117 shall ye eatH398 unleavenedH4682 breadH4682; even the firstH7223 dayH3117 ye shall put away leavenH7603 out of your housesH1004: for whosoever eateth leavenedH2557 breadH4682 from the firstH7223 dayH3117 until the seventhH7637 dayH3117, that soulH5315 shall be cutH3772 off from IsraelH3478. 16And in the firstH7223 dayH3117 there shall beH1961 to you a holyH6944 convocationH4744, and in the seventhH7637 dayH3117 a holyH6944 convocationH4744; no manner of workH4399 shall beH1961 done in them, save that which every man must eatH398, that onlyH389 may beH1961 done by you. 17And ye shall observeH8104 the feast of unleavenedH4682 breadH4682; for in this selfsame dayH3117 have I broughtH3318 your hostsH6635 out of the landH776 of EgyptH4714: therefore shall ye observeH8104 this dayH3117 throughout your generationsH1755 by an ordinance for everH5769.
