As Moses prepared the hearts of Israel for his departure by means of death, he reminded them of the Passover, and then the Feast of Unleavened Bread, saying about the latter,
“Six days you shall eat unleavened bread, and on the seventh day there shall be a sacred assembly to the LORD your God. You shall do no work on it” (Deuteronomy 16.8).
Every generation of Israel was to eat unleavened bread for seven days after the Passover, reminding them of their escape out of Egypt, that their forefathers had no time to allow bread to rise and then bake it for the journey, but they had to get out of Egypt as quickly as possible, lest Pharaoh change his mind, as he had done before, and truly later he did regret having let Israel go.
For an entire week, Israelite families would not have any leaven, and so as they ate the bread, they would remember how they just barely escaped slavery.
On the seventh day, the Lord wanted them to have a sacred assembly dedicated to Him.
Today, Christians should eat the Lord’s Supper every first day of the week, which includes unleavened bread, reminding us of the pure body of Christ, and that He by His horrible death freed us from spiritual slavery.
