Verse 10. - This ordinance. The ordinance of unleavened bread. See Exodus 12:14, 24.

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.Thou shall therefore keep the ordinance in his season,.... Not the ordinance of the phylacteries, as the Targum of Jonathan, but the ordinance of unleavened bread:

from year to year; every year successively, so long as in force, even unto the coming of the Messiah. It is in the Hebrew text, "from days to days" (c); that is, either year after year, as we understand it; or else the sense is, that the feast of unleavened bread, when the season was come for keeping it, was to be observed every day for seven days running.

(c) "a diebus in dies", V. L. Montanus, Munster, Vatablus, Drusius.
