Exodus 12:14 WBT

¹²  For I will pass through the land of Egypt this night, and will smite all the first-born in the land of Egypt, both man and beast: and against all the gods of Egypt I will execute judgment: I [am] the LORD.

¹³  And the blood shall be to you for a token upon the houses where ye [are]: and when I see the blood, I will pass over you, and the plague shall not be upon you to destroy [you], when I smite the land of Egypt.

¹⁴  And this day shall be to you for a memorial; and ye shall keep it a feast to the LORD throughout your generations: ye shall keep it a feast by an ordinance for ever.

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

¹⁶  And in the first day [there shall be] a holy convocation, and in the seventh day there shall be a holy convocation to you: no manner of work shall be done in them, save [that] which every man must eat, that only may be done by you.
