Exodus 13:6-10

VIN(i) 6 Seven days shalt thou eat unleavened, and in the seventh day a festival to the LORD. 7 Unleavened bread will be eaten the seven days; food with yeast will not be seen for you; and yeast will not be seen for you in all your territory. 8 "On that day tell your children: 'We do this because of what the LORD did for us when we left Egypt.'" 9 And it will be for a sign to you upon your hand and for a memorial between your eyes, that the law of the LORD may be in your mouth, because the LORD has brought you out of Egypt with a strong hand. 10 You shall keep this ordinance at its appointed time from year to year."
