17And ye shall observeH8104 the feast of unleavened breadH4682; for in this selfsameH6106 dayH3117 have I broughtH3318 your armiesH6635 out of the landH776 of EgyptH4714: therefore shall ye observeH8104 this dayH3117 in your generationsH1755 by an ordinanceH2708 for everH5769.

18In the firstH7223 month, on the fourteenthH702H6240 dayH3117 of the monthH2320 at evenH6153, ye shall eatH398 unleavened breadH4682, until the oneH259 and twentiethH6242 dayH3117 of the monthH2320 at evenH6153. 19SevenH7651 daysH3117 shall there be no leavenH7603 foundH4672 in your housesH1004: for whosoever eatethH398 that which is leavenedH2556, even that soulH5315 shall be cut offH3772 from the congregationH5712 of IsraelH3478, whether he be a strangerH1616, or bornH249 in the landH776. 20Ye shall eatH398 nothing leavenedH2556; in all your habitationsH4186 shall ye eatH398 unleavened breadH4682.
