Exodus 12:15 DBY

¹³  And the blood shall be for you as a sign on the houses in which ye are; and when I see the blood, I will pass over you; and the plague shall not be among you for destruction, when I smite the land of Egypt.

¹⁴  And this day shall be unto you for a memorial; and ye shall celebrate it [as] a feast to Jehovah; throughout your generations [as] an ordinance for ever shall ye celebrate it.

¹⁵  Seven days shall ye eat unleavened bread: on the very first day ye shall put away leaven out of your houses; for whoever eateth leavened bread from the first day until the seventh day -- that soul shall be cut off from Israel.

¹⁶  And on the first day ye shall have a holy convocation, and on the seventh day a holy convocation: no manner of work shall be done on them, save what is eaten by every person -- that only shall be done by you.

¹⁷  And ye shall keep the [feast of] unleavened [bread]; for in this same day have I brought your hosts out of the land of Egypt; and ye shall keep this day in your generations [as] an ordinance for ever.
