The Feast of Unleavened Bread began with the Passover meal and continued for seven more days (v. 15). The bread that the Jews used contained no leaven (yeast), which made it like a cracker rather than cake in its consistency. The Old Testament uses leaven as a symbol of sin often. Leaven gradually permeates dough, and it affects every part of the dough. Here it not only reminded the Israelites in later generations that their ancestors fled Egypt in haste, before their dough could rise. It also reminded them that their lives should resemble the unleavened bread as redeemed people. Bread is the staff of life and represents life. The life of the Israelites was to be separate from sin since they had received new life as a result of God's provision of the Passover lamb. Eating unleavened bread for a week and removing all leaven from their houses would have impressed the necessity of a holy life upon the Israelites.
"For us the leaven must stand for the selfness which is characteristic of us all, through the exaggerated instinct of self-preservation and the heredity received through generations, which have been a law to themselves, serving the desires of the flesh and of the mind. We are by nature self-confident, self-indulgent, self-opinionated; we live with self as our goal, and around the pivot of I our whole being revolves."210
Anyone who refused to abide by these rules repudiated the spiritual lesson contained in the symbols and was therefore "cut off from Israel."This phrase means to experience separation from the rights and privileges of the nation through death.211
The Israelites celebrated the Passover on the fourteenth of Abib, and the Feast of Unleavened Bread continued through the twenty-first (v. 18). God's call to the Israelites to live holy lives arose from what God had done for them. Consecration follows redemption; it is not a prerequisite for redemption. Similarly God calls us to be holy in view of what He has done for us (cf. Rom. 12:1-2). He does not say we can experience redemption if we become holy first.
Sunset ended one day and began the next for the Jews.
