And on the fifteenth day of this month is the feast of unleavened bread to the Lord; seven days shall ye eat unleavened bread.
On the fifteenth day of the same month begins the Feast of Unleavened Bread (note: That is, the seven-day period after the Passover during which no leaven may be eaten; see Exodus 12:14–20.) to the LORD. For seven days you must eat unleavened bread.
