[18] In the first month, on the fourteenth day of the month at even, ye shall eat unleavened bread, until the one and twentieth day of the month at even. [19] Seven days shall there be no leaven found in your houses: for whosoever eateth even that soul shall be cut off from the congregation of Israel, whether he be a stranger, or born in the land. [20] Ye shall eat in all your habitations shall ye eat unleavened bread.
