Exodus 12:15 - Exposition

Seven days. There is no indication that the week of seven days was admitted by the ancient Egyptians, or even known to them. Apparently, the nation which first adopted it was that of the Babylonians. Abraham may have brought it with him from "Ur of the Chaldees;" and from him it may have passed to Jacob, and so to Moses. That the week was known in the family of Abraham before the giving of the law, appears from Genesis 29:27 , Genesis 29:28 . Unleavened bread is typical of purity of heart, leaven being an emblem of corruption ( Matthew 16:6-12 ; 1 Corinthians 5:7 ). "Leaven," says Plutarch, "comes from corruption, and corrupts the dough with which it is mixed; and every fermentation seems to be a putrefaction." The primary command to celebrate the first passover with unleavened instead of leavened bread ( Genesis 29:8 ), must be attributed wholly to this symbolism. But the permanent institution of a "feast of unleavened bread," to last a week, had a double bearing. Partly, it was designed to deepen and intensify the conviction that corruption and impurity disqualify for religions service; but it was also partly intended as a commemoration of the fact, that in their hasty flight from Egypt the bread which they took with them was unleavened The requirement to "put away leaven out of their houses" is probably intended to teach, that for family worship to he acceptable, the entire household must be pure, and that to effect this result the head of the household must, so far as he can, eject the leaven of sin from his establishment. Whosoever eateth … shall be out off from Israel . Expelled, i.e , from the congregation, or excommunicated. If a man wilfully transgresses any plain precept of God, even though it be a positive one, he should he severed from the Church, until he confess his fault, and repent, and do penance for it. Such was the ', godly discipline" of the primitive Church; and it were well if the Churches of these modern times had more of it.
