13:7 There shall no leavened bread be seen in all thy quarters - Accordingly the Jews usage was, before the feast of the passover, to cast all the leavened bread out of their houses; either they burnt it, or buried it, or broke it small, and threw it into the wind; they searched diligently with lighted candles in all the corners of their houses, lest any leaven should remain. The strictness enjoined in this matter was designed, To make the feast the more solemn, and consequently the more taken notice of by the children, who would ask, why is so much ado made? To teach us how solicitous we should be to put away from us all sin.
13:1-10 In remembrance of the destruction of the first-born of Egypt, both of man and of beast, and the deliverance of the Israelites out of bondage, the first-born males of the Israelites were set apart to the Lord. By this was set before them, that their lives were preserved through the ransom of the atonement, which in due time was to be made for sin. They were also to consider their lives, thus ransomed from death, as now to be consecrated to the service of God. The parents were not to look upon themselves as having any right in their first-born, till they solemnly presented them to God, and allowed his title to them. That which is, by special mercy, spared to us, should be applied to God's honour; at least, some grateful acknowledgment, in works of piety and charity, should be made. The remembrance of their coming out of Egypt must be kept up every year. The day of Christ's resurrection is to be remembered, for in it we were raised up with Christ out of death's house of bondage. The Scripture tells us not expressly what day of the year Christ rose, but it states particularly what day of the week it was; as the more valuable deliverance, it should be remembered weekly. The Israelites must keep the feast of unleavened bread. Under the gospel, we must not only remember Christ, but observe his holy supper. Do this in remembrance of him. Also care must be taken to teach children the knowledge of God. Here is an old law for catechising. It is of great use to acquaint children betimes with the histories of the Bible. And those who have God's law in their heart should have it in their mouth, and often speak of it, to affect themselves, and to teach others.
